telo118 [61]

Answer:

TA is greater than TB

T_{A} > T_{B}

Explanation:

Specific heat at constant pressure C_{p} is greater than specific heat at constant volume C_{v}.Therefore for given amount of supplied heat,increase in temperature at constant volume is greater than increase in temperature at constant pressure

Hence

TA is greater than TB

T_{A} > T_{B}

A 2.0-kg silverware drawer does not slide readily. The owner gradually pulls with more and more force, and when the applied forc
topjm [15]

Answer: 0.45

Explanation:

First note that the body that causes the body to move is its moving force (Fm) which is 9.0N

Since the mass of the body is 2.0kg, the weight will be;

W= mg = 2×10

W= 20N

For static body, the frictional force (Ff) acting on the body is equal to the moving force (Fm) since both forces acts along the horizontal on the body.

Ff = Fm = 9.0N

The normal reaction (R) on the body will also be equal to its weight(W) since weight acts downwards and the reaction acts in the opposite direction (upwards).

R = W = 20N

Ff = nR taking 'n' as coefficient of static friction between the drawer and the cabinet.

9.0 = 20n

n = 9/20

n = 0.45

How does temperature,barometric pressure,humidity,wind speed and direction, and precipitation determine the weather in a particu
Deffense [45]
Temperature is how hot or cold something is,barometric is air pressure(when the pressures high,the weather is dry)humidity is how moist the air is and how many water particles are there, wind speed and direction is how the hot and cold air is moving and how fast,which makes wind (high to low, hot to cold) precipitation is how much it is raining at that point.

You are in a spacecraft moving at a constant velocity. The front thruster rocket fires incorrectly, causing the craft to slow do
Alchen [17]

Answer:

It continue to move forward at a constant velocity which will be slower than before the front thruster was fired.

Explanation:

Before the front thruster was fired, the spacecraft was already moving at a particular velocity.

After the malfunction, the front thruster is fired and then the force exerted by that front thruster slows the spacecraft down, as we are told.

By using the rear thruster to exert a force equal to that from the front thrusters, a force equal in magnitude to that of the front thrusters is added, cancelling out the effect of the front thrusters. Because the spacecraft is already moving at a slower speed at this point compared to the beginning, it continues to move at that speed.
