An ant is crawling along a yardstick that is pointed with the 0-inch mark to the east and the 36-inch mark to the west. It starts at the 17-inch mark, crawls to the 21-inch mark, then moves to the 8-inch mark. What was the total distance the ant traveled?

The ball's velocity after it has travelled a total distance of 50.0 meters is 40.63 m/s

The following data were obtained from the question:

We can obtain the final velocity as illustrated below:

v² = u² + 2gh

v² = 25.9² + (2 × 9.8 × 50)

v² = 670.81 + 980

v² = 1650.81

Take the square root of both sides

v = √1650.81

v = 40.63 m/s

Thus, the velocity after travelling 50 m is 40.63 m/s

The block's oscillation frequency is 1.1 Hz.

The block's distance from equilibrium when the speed is 57 cm/s  is 14.2 cm.

The block's distance from equilibrium at t = 7.0 s  is 10.37 cm.

The oscillation frequency of the block is calculated as follows;

f = 1/2π√(k/m)

f = 1/2π √(9/0.19)

f = 1.1 Hz

ω = 2πf

ω = 2π x 1.1

ω = 6.91 rad/s

x(t) = A cos(ωt + Φ)

ωX sin(Ф) = v

6.91 x 29 sin(Ф) = 116

sin(Ф) = 116/200.39

sin(Ф) = 0.579

Ф = arc sin(0.579)

Ф = 0.62 rad

29 = A cos(6.91 x 0  +  0.62)

29 = A cos(0.62)

29 = A(0.814)

A = 35.63 cm

when the speed is 57 cm/s, the distance of the block is calculated as follows;

ωX sin(Ф) = v

(6.91)X sin(0.62) = 57

X(4.015) = 57

X = 57/4.015

X = 14.2 cm

x(t) = A cos(ωt + Φ)

As per the given question;

On a dry day, a mirror or window polished with a dry cloth quickly develops dust. Dry cloth friction on glass produces charged static electricity, which attracts microscopic non-charged dust particles.

Static electricity can cause problems or even pose a risk. Your hair standing on end energy can also destroy electronics and cause explosions. However, it can also be a huge asset to modern life when properly managed and manipulated.

When the positive and negative charges are out of balance, static electricity is produced. While electrons like to jump all over the place, protons and neutrons don't move around that much. A negative charge is present when an object (or person) has extra electrons.

Answer: It is true.

Explanation: In all atoms, the number of electrons and protons is always equal. This preserves the atom's electrical neutrality by balancing positive and negative charges. If the amount of electrons and protons in an atom is not equal, the atom will have a net positive or negative charge, forming a cation or an anion.

The time taken for the train to stop is 8.9 seconds.

The distance traveled by the train during acceleration is 9,984 m.

The distance traveled by the train during deceleration is 17.8 m.

Use the following kinematic equation to determine the time taken for the train to stop.

v = u + at

where;

0 = 4 - 0.45t

0.45t = 4

t = 4/0.45

t = 8.89 seconds = 8.9 seconds

s = ut + ¹/₂at²

where;

s = (4)(480) +  ¹/₂(0.07)(480)²

s = 9,984 m

s = ut + ¹/₂at²

s = (4 x 8.9) + ¹/₂(-0.45)(8.9)²

(0.43 ± 0.08)m/s is the speed of the ball.

Velocity is the pace and direction of an object's movement, whereas speed is the time rate at which an object is traveling along a path. Speed can be thought of as the rate at which an object travels a distance, and it is a scalar quantity that denotes "how rapidly an object is traveling."

A fast-moving object travels at a high speed and completes a significant distance in a brief period of time. This is in contrast to an object traveling slowly, which travels a relatively short distance in the same length of time. Zero speed refers to an object that is not moving at all.

RPM is not a unit, according to the International System of Units (SI). The word "revolution" is a semantic annotation rather than a unit, which explains this. RPM formula sign must be f for (rotational) frequency and or for angular velocity due to the measured physical quantity. s−1  or Hz is the basic SI-derived unit that corresponds. The radians per the second unit are used to express angular speed.

The average speed you must run is 7.97 mph.

The average speed of an object is the ratio of total distance traveled by the object to

Average speed = total distance / total time of motion

Total time of motion = total distance / average speed

total time = (18.5 + 5.5) / (14.5)

total time = 1.66 hours

t1 = 18.5 / 19.1

t1 = 0.97 hour

t2 = 1.66 hr - 0.97 hr

t2 = 0.69 hr

v = 5.5 miles /0.69 hr

v = 7.97 mph

The train is not an inertial frame of reference, and the train may be moving at a constant speed in a straight line or the train may be instantaneously at rest.

The pace at which an object's position changes about relation to a frame of reference and time is known as its velocity.

Uniform velocity is the state in which a body travels the same distance in the same amount of time. When the amplitude and direction of a body's average velocity (v) over time (t) do not change over time, the body is said to be moving at a uniform velocity. An illustration of uniform motion is the moon's orbit around the earth.

As the rate of change of velocity, acceleration is an illustration of a vector quantity.

The entire motion of an object, regardless of direction.

In physics, motion is that the phenomenon in which an object changes its position with respect to time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and frame of regard to an observer and measuring the change in position of the body relative to that frame with change in time. The branch of physics describing the motion of objects without regard to their cause is called kinematics, while the branch studying forces and their effect on motion are named dynamics.

If an object isn't changing relative to a given frame of reference,  the thing is said to be at rest, motionless, immobile, stationary, or to possess a constant or time-invariant position with reference to its surroundings. Modern physics holds that, as  there's no absolute frame of reference, Newton's concept of absolute motion can't be  determined
