Answer:

hello your question is incomplete below is the complete question

Devon has several toy car bodies and motors. The motors have the same mass, but they provide different amounts of force, as shown in the table.

Which motor and body should Devon use to build the car with the greatest acceleration?

motor 1, with body 1

motor 1, with body 2

motor 2, with body 1

motor 2, with body 2

answer: Motor 2 body 1

Explanation:

F = ma

hence a ( acceleration ) = F / m

force of motor 2 = 15 N since the mass of the motor is the same and that of the bodies aren't given

The motor and body that would produce the greatest acceleration would be : Motor 2 Body 1  if the mass of Body 1 is less than the mass of Body 2

A 55.0-g sample of hot metal initially at 99.5oC was added to 40.0 g of water in a Styrofoam coffee cup calorimeter. The water a
Kaylis [27]

Answer:

Cp= 0.44 J/g.C

This is heat capacity of metal.

Explanation:

From energy conservation

Heat lost by metal = Heat gain by water +Heat gain by  calorimeter

Because here temperature of metal is high that is why it loose the heat.The temperature of water and  calorimeter is low that is why they gain the heat.

final temperature is T= 30.5 C

We know that sensible heat transfer given as

Q= m Cp ΔT

m=Mass

Cp=Specific heat capacity

ΔT=Temperature difference

By putting the values

55 x Cp ( 99.5 - 30.5) = 40 x 4.184 ( 30.5- 21 ) + 10 x ( 30.5 - 21)

Cp ( 99 .5- 30.5) = 30.65

Cp= 0.44 J/g.C

This is heat capacity of metal.

A 70-kg ice skater is standing still on the ice, when a friend tosses him a 10-kg ball that is traveling at +8 m/s. If he catche
Misha Larkins [42]

Answer:+1.25 m/s

Explanation:

Given

mass of ice skater M=70 kg

mass of ball m=10 kg

the initial velocity of the ball  u_1=+8\ m/s

Conserving linear momentum

M\times0+m\timesu_1=(M+m)v\quad \quad [v=\text{combined velocity of skater and ball}]

v=\dfrac{10\times10}{80}=+1.25\ m/s

Therefore the velocity of the person holding the ball is 1.25 m/s

This collision represents the perfectly inelastic collision where particles stick together after the collision.

1. A gas is kept at a pressure of 22Kpa and a temperature of 287K. What will
Ann [662]

Answer:

New pressure (P2) = 22.92 Kpa (Approx)

Explanation:

Given:

Old pressure (P1) = 22 Kpa

Temperature (T1) = 287 K

Temperature (T2) = 299 K

Find:

New pressure (P2)

Computation:

P1 / T1 = P2 / T2

22 / 287 = P2 / 299

New pressure (P2) = 22.92 Kpa (Approx)
