The things that could be true about the object A should that it could be either positive or negative in charge.

Every object having mass has some charge on it, here, the object B is negatively charged and the object A is the attracted by the object B when they are brought close to each other.

By the standard rules, we know, that the opposite charges attract each other, on the other hand a neutral object is always attracted by other charges objects irrespective of the their charge.

So, as it is stated that object B is negatively charged, it is obvious that the object A will be either positive or neutral in nature in terms of charge.

Pascal's law of fluid transfer states that when there is an increase in fluid pressure, the rest of the extrinsic variables also increases.

For example, in a flow of liquid in an orifice, there is a contraction of diameter in the orifice part. The fluid that will go in there increases in pressure and thereby an increase in velocity as well. As per Pascal's law of pressure transmission we know that pressure at a point has many direction, and hence a pressure change at any point in a confined fluid is transmitted throughout the fluid such that the same change occurs everywhere.

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.

The total Resistance is 14 ohm, Current is V/14 and Power is V²/14.

About Ohm's law

Ohm's law is one of the physics that is quite close to everyday life, because in everyday life, of course, we cannot be separated from electronic devices. As is known, almost all electronic devices require electricity to be turned on or operated. Every electrical device has different voltages, depending on their needs.

When the electricity supplied exceeds the required limit of the device, it is likely that the device will be damaged. Electricity itself appears because basically every object contains two types of charge, namely positive (protons) and negative (electrons). And when the negative charge or electrons move, an electric current will appear.

A) The circumference of the track is equal to the distance traveled by the runner in one lap, or C=vt, where v is the velocity and t is the time. So the radius of the track is approximately 70.11 m.

B) The centripetal acceleration is the acceleration towards the center of the circle. So the runner's centripetal acceleration during the run was approximately 0.25 m/s^2.

Centripetal acceleration is a type of acceleration that acts in a direction that is towards the center of a circular path. It is defined as the rate of change of the velocity vector of an object moving in a circular path. The magnitude of centripetal acceleration is given by the equation a = v^2/r, where v is the velocity of the object and r is the radius of the circular path.

Centripetal acceleration is responsible for keeping an object moving in a circular path. Without centripetal acceleration, the object would fly off in a straight line clue to its tangential velocity.

The energy that allows a super bouncy ball to bounce up from the ground after being dropped from a height of 5m comes from the potential energy that was stored in the ball when it was elevated.

When the ball is dropped, it gains kinetic energy as it falls, and when it strikes the ground, that kinetic energy is transformed into other forms of energy, including thermal and elastic energy. The elastic energy stored in the ball's compressed material then pushes it back up into the air, converting back into kinetic energy as it rises and then potential energy as it reaches its peak height. The ball continues to lose energy to thermal and other forms, causing it to eventually lose enough energy to stop bouncing.

If the velocity of the particle when x=-2 m. The velocity of the particle is +4.70 m/s.

Velocity is a measure of the rate at which an object changes its position in a given direction. It is a vector quantity, meaning that it has both magnitude and direction. The magnitude of velocity is the speed of an object, and the direction is the path that the object takes. In physics, velocity is defined as the rate of change of an object's position with respect to time. It is expressed mathematically as the derivative of position with respect to time, or v = dx/dt.

The velocity of a particle can be constant, meaning that it moves at a constant speed in a straight line, or it can be changing, meaning that the speed or direction of the particle is changing.

What is angular speed?

An angular speed is a speed of an object in rotational motion. The angular speed in relation to linear speed is

ω = vr

Where

ω = angular speedv = linear velocityr = radius of a circle

The wheel on a car is spinning.

ω = 625 rev/minIt travels 8 feet/revolution

Find the linear speed of the wheel!

1 revolution means a circle of the wheel. The perimeter of the wheel is 8 feet.

The radius of the wheel is

P = 2πr

8 = 2(3.14)r

r = 8/6.28

r = 1.274 feet

r = 1.274 × 0.3048 m

r = 0.3883 m

We change the unit of angular speed to rad/s.

ω = 625 rpm

ω = 625 × 2π/60 rad/s

ω = 65.42 rad/s

The linear speed will be

ω = vr

65.42 = v(0.3883)

v = 65.42/0.3883

v = 168.5 m/s

Remember that 1 m/s = 2.237 mph.
