The speed of car is 106.67 miles per hour

To solve problems involving speed and distance we are required to first find speed or distance travelled in an hourly timeframe

It is given that car takes 4 hours to cover the distance at a speed of 40 miles per hour

Therefore, total distance travelled by the car= speed x time

                                                                          = 40 miles per hour x 4 hour

                                                                          =160 miles

We are required to find the speed of the car if the distance is to be covered in 1.5 hours

We are required to find the speed by the formula speed= Distance/time

distance= 160 miles     time = 1.5 hour

speed= 160/1.5=106.666=106.67 miles per hour

Hence the speed is 106.67 miles per hour

Crushing increases the ice's surface area. Additionally, cooling from ice happens as a result of convection, which is proportional to area. Thus, breaking up the ice expedites the cooling process.

When precise and consistent temperature control inside a process is necessary, this sort of cooling is used. Because they can offer cooling capacity independent of variations in the ambient temperature, heat load, and flow needs of the application, chillers are frequently employed to remove heat from a process.

It's important to properly regulate the heat load in many industrial operations. Different components of the whole application might need to be cooled.

Major locations for cooling include:

Direct product cooling

During the molding process, plastic

Answer:

the ball will travel for 2 seconds and complete a distance of 20 metres upwards.

Explanation:

v = final velocity

u = initial velocity

a = acceleration

t = time

s = distance

In your question, the initial velocity is given as 20m/s , i.e., u=20m/s ,

the final velocity that the ball can achieve at the maximum height is 0m/s

, hence, v=0m/s .

Since the only first that cause the acceleration is gravity, a is taken as g where g is acceleration due to gravity, and had a value of 9.81m/s2 . But for simplicity, we can take the value of a to be 10m/s2 , so a=10m/s2 . Now, we need to find, what's s and t.

Note: Since the ball is thrown upwards, which is against the force of gravity (gravity always acts downwards), we need take the value of a (in this case, g) as −10m/s2 .

Using the first equation,

v=u+at

0=20−10t

10t=20

t=2

Using the third equation,

v2=u2+2as

02=202+2×(−10)×s

20s=400

s=20

Hence, the ball will travel for 2 seconds and complete a distance of 20 metres upwards.

The correct answer is 0.75 liters.

One liter of soda produced 250 ml of beverage.

1 liter is equal to 1000 milliliters.

250 ml was consumed, or 250/1000 or 0.25 liter.

There was 1 - 0.25 liters of soda left

0.75 liter of soda was left and the correct answer is 0.75 liter.

Four glasses of water make up one liter, to be precise.

Let us understand this using the following explanation. Despite the fact that there is no set standard size for glasses, their capacity varies. In contrast, we calculate that a liter holds 32 ounces and a glass holds 8 ounces of water.

Convert the object's dimensions into centimeters before performing the volume calculation in litres. Next, determine a shape's volume using the volume formula. For instance, you could use Volume = length times width times height to determine the volume of a cube, and the result would be in cubic centimetres.

The space between the screen fringes will be closed if the complete apparatus is submerged in water.

The space between two consecutive bright spots (maximas, when constructive interference occurs), or two consecutive dark patches, is known as the fringe width (minimas, where destructive interference occurs). All of the fringes in Young's double-slit experiment are the same length. The formula yields the fringe width. β = λD/d. Because it depends on L, the spacings between various fringes get smaller as the slit distance gets bigger. Since the space between various fringes is wavelength dependent, increasing the light's wavelength also increases that separation.

In comparison to air, water has a shorter wavelength of light. Therefore, when the device is submerged in water, the fringe width will diminish.

The correct answer for the affect in the stage capacity is that it will increase.

The stage's capacity will increase .

The capacity formula is as follows:

Capacity = (Batch size) / (Total setup time + processing time x batch size) 

Clearly, increasing the batch size twice will increase capacity, but not in the same proportion because the batch size is the same in the numerator and denominator. Increasing the batch size will increase the capacity but in very small proportions. Furthermore, if the batch size is too large, goods will be produced even if there is no demand, and if the batch size is too small, capacity will be lost. As a result, there is a trade-off between batch size and capacity.

Answer:

i. Point A

ii. None

iii. All points

iv. F

v. None

vi. All

vii. None

Explanation:

i. Not quite sure if I'm interpreting the diagram right, but from the second the ball is released, it will start accelerating. Point A is where the velocity will be closest to 0 but not necessarily 0 as it will have started accelerating downwards.

ii. Assuming standard directions for vectors, the velocity is positive at none of the points as the ball is travelling in a downwards direction.

iii. Since the ball is always travelling downwards, its direction and therefore velocity is a negative number at all points in this diagram.

iv. The ball is accelerating as it falls so the further or the longer it falls, the faster its velocity, therefore in this diagram, it is fastest at point F.

v and vi. Assuming same direction principles as ii and iii (as acceleration and velocity are both vectors), acceleration is always downwards, therefore it is positive at no points, and negative at all of them.

vii. Acceleration due to gravity is always constant, so unless the ball is not moving (being held by the boy), acceleration is not 0 at any of the points.

If a train starts from rest and accelerates uniformly until it has traveled 7.1km and acquired a forward velocity of 36m/s. the train then moves at a constant velocity of 36m/s for 2.1min. The train then slows down uniformly at 0.072m/s^2, until it is brought to a halt.  Then the entire process take (in minutes ), approximately 17.1 minutes.

Here, we have the following values,

u = 0

Now to find acceleration (a), a = [tex]\frac{36 *36}{2*7100}[/tex] = 0.091 m/[tex]s^{2}[/tex]

Now we know that a = 0.072 v = 0 u = 36 m/s then for t
