It has been proposed to use uranium carbide (UC) for the initial fuel in certain types of breeder reactors, with the uranium enriched to 25 w/o. The density of UC is 13.6 g/cm3 . The molecular weight of U-235 and U-238 are 235.0439 and 238.0508 respectively. (a) What is the atomic weight of the uranium? (b) What is the atomic density of U-235?
(a) The atomic weight of uranium can be calculated as a weighted average of the atomic weights of the isotopes U-235 and U-238, taking into account their natural abundances. The atomic weight of uranium is approximately 238.03 g/mol.
(b) To calculate the atomic density of U-235, we need to know the mass fraction (or weight fraction) of U-235 in uranium carbide fuel. Considering that uranium is enriched to 25 w/o U-235, the mass fraction of U-235 is 0.25. The atomic density of U-235 can then be calculated as follows:
atomic density = (mass fraction of U-235) * (UC density) / (atomic weight of U-235)
= (0.25) * (13.6 g/cm3) / (235.0439 g/mol)
= about 7.07 x 10^22 atoms/cm3

Required information Problem 11.009 - Slowing car - DEPENDENT MULTI-PART PROBLEM - ASSIGN ALL PARTS NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. The brakes of a car are applied, causing it to slow down at a rate of 18 ft/s2. The car stops at 300 ft. 300 ft Problem 11.009.a - Slowing car: constant deceleration and distance traveled Determine how fast the car was traveling immediately before the brakes were applied. (You must provide an answer before moving to the next part.) The speed of the car immediately before the brakes were applied was ft/s. Problem 11.009.b - Slowing car: constant deceleration and elapsed time Determine the time required for the car to stop. The time required for the car to stop is S.
The acceleration is 7m/s².
For Part a, we can use the equation of motion for constant acceleration:
v f = v_0 + a x t
where v f is the final velocity, v_0 is the initial velocity, a is the acceleration, and t is the time. Since the final velocity is 0, we can write:
t = -v 0 / a
Next, we can use the distance formula:
d = v_0 x t + 0.5 x a x t²
where d is the distance traveled. Plugging in the value of t from the previous equation, we get:
d = v_0 x (-v_0 / a) + 0.5 x a x (-v_0 / a)²
d = -v_0² / 2a
Now, we can solve for v_0 using the value of d:
v_0 = (2 x a x d) = (2 x 18 x 300)= 102.9 feet/s
For Part b, we can use the equation for t from Part a:
t = -v_0 / a = -102.9 / 18 = 5.71 s
Acceleration is the rate of change of velocity of an object over time. It is a vector quantity with units of meters per second squared (m/s²) in the SI system. Acceleration can be caused by various factors such as force, changes in velocity, and changes in direction. Positive acceleration indicates that the velocity of an object is increasing, while negative acceleration indicates that the velocity is decreasing. In a uniform acceleration, the velocity of an object changes by an equal amount over equal time intervals.

A). The average velocity (in m/s) over the given time intervals is 7.94 m/s.
B). This value is the instantaneous velocity of the rock at t = 1 s, which is approximately 7.94 m/s.
The average velocity of the rock can be found using the formula: average velocity = (final position - initial position) / (final time - initial time).
(a) [1, 2] s: average velocity = (14(2) - 14(1) - 1.86(2^2) + 1.86(1^2)) / (2 - 1) = 4.14 m/s
[1, 1.5] s: average velocity = (14(1.5) - 14(1) - 1.86(1.5^2) + 1.86(1^2)) / (1.5 - 1) = 5.61 m/s
[1, 1.1] s: average velocity = (14(1.1) - 14(1) - 1.86(1.1^2) + 1.86(1^2)) / (1.1 - 1) = 7.31 m/s
[1, 1.01] s: average velocity = (14(1.01) - 14(1) - 1.86(1.01^2) + 1.86(1^2)) / (1.01 - 1) = 7.88 m/s

(b)This value is the instantaneous velocity of the rock at t = 1 s, which is approximately 7.94 m/s.
Average velocity is a measure of the overall rate of motion of an object over a certain time period. It is different from average speed, which is a measure of the total distance traveled over a certain time period. Average velocity takes into account not only the distance traveled, but also the direction of motion.
Average velocity is calculated by dividing the change in position (displacement) by the time interval over which the motion occurs. It is expressed in units of distance per unit time, such as meters per second or miles per hour. The formula for average velocity is given by v = Δx / Δt, where Δx is the change in position and Δt is the change in time.
Average velocity is commonly used in physics and engineering to determine the motion of objects in one-dimensional systems, such as along a straight line. For example, the average velocity of a car traveling from one location to another can be determined by measuring the change in its position over a certain time period.

A block of white color is kept on a table. Suppose you are looking at this block through a glass which allows only red light to pass through it. What would be the color of the block as seen by you using the glass
Answer:
red
Explanation:
The color of the block as seen by you using the glass would be red.
When white light passes through a red filter, only the red portion of the light is allowed to pass through. The other colors (blue, green, yellow, etc.) are absorbed by the filter. So, when you look at the white block through a red filter, you will only see the red portion of the light reflected off the block, making it appear red to your eye.
Answer:
Red only
Explanation:
The colour of the block as seen by you using the glass would be red.
two stones are thrown vertically upward from the ground, one with three times the initial speed of the other. assume free fall.
Stone speed is equal to three times stone speed if the stones are the same size. The stone will touch the earth in 10/3s, or 3.3 seconds because gravity will affect both stones equally during the fall.
When a stone is thrown vertically upward, what two forces are at work on the object?Gravitational force acts downhill when a stone is propelled vertically, while muscular force or an applied force acts upward.
Why does a stone being hurled vertically upward lose speed?Gravity tries to pull the stone down when it is thrown vertically upward, slowing down its motion. After a period, the velocity falls to zero as a result of this persistent downward drag.

the photograph below shows a girl pushing on a large stone sphere. the sphere has a mass of 8200 kg and a radius of 90 cm and floats with nearly zero friction on a thin layer of pressurized water.
The time that will take the girl to rotate the sphere one time (the sphere has a mass of 8200 kg and a radius of 90 cm and floats with nearly zero friction on a thin layer of pressurized water) starting from rest = 35.16 s
To determine the time it's take the girl to rotate, use the intertia formula:
I = ⅖ (m) (r²)
Where,
I = inertia
m = mass of the object (kg)
r = radius
Hence,
I = ⅖ (8200) (0.9)²
= 2657 kgm²
Determine the torque,
τ = (I)(α)
(30) (0.9) = (2657) α
α = 0.01016 rad/s²
Θ = ½(α) (t²)
2π rads = ½ (0.01016) (t²)
t =sqrt(4π 0.0106)
t = 35.16 s

for general projectile motion, which of the following best describes the horizontal component of a projectile's acceleration? assume air resistance is negligible.
Assume there is little air resistance the acceleration of a projectile has no horizontal component.
What happens to a projectile's horizontal component of velocity in a projectile's typical motion?The object is moved downward from its position if gravity didn't exist as a result of the downward force and acceleration. A projectile maintains the same angular momentum because there are no horizontally forces acting on it, hence the force of gravity has no effect on the angular position of motion.
Is there zero acceleration in the horizontal component?The speed, which is larger than 115 m/s as expected, is a result of both vertical and horizontal velocity components. As seen in Figure 3.10, the velocity vector forms an aspect q with the horizontal: A crucial aspect of falling object.

A wheel of radius $a$ rolls along a horizontal straight line without slipping. Find parametric equations for the curve traced out by a point $P$ on a spoke of the wheel $b$ units from its center. As parameter, use the angle $\theta$ through which the wheel turns. The curve is called a trochoid, which is a cycloid when $b=a$
The position of point $P$ relative to the center of the wheel can be described as follows:
$x = a\theta - b\sin\theta$
$y = a - b\cos\theta$
$a$ is the radius of the wheel and $b$ is the distance of point $P$ from the center of the wheel. These equations define a trochoid. If $b = a$, then it becomes a cycloid.
About radiusThe radius is a circle is the line that connects the center point of the circle to a point on the circle. In a 3-dimensional sphere, the radius that connects the center of the ball to a point on the surface of the ball. The radius of a circle is half the diameter of the circle.
