Answer:

Mass = 40 kg

Velocity = 3m/s

Kinetic energy = mv^2/2

= 40 x 3 x 3/2

= 180 J

Hope this helps!

Chemical energy stored in food cannot be transformed into mechanical energy true or false
Orlov [11]
If that statement were true, then you would never have any reason to eat.
It might taste good for a while, but it would never help you stand up and
move around.

Where WOULD you get the energy to stand up and walk, if it didn't
come from food ? ?

The whole idea is pretty absurd.  I guess the statement is not true.

In which type of process is a gas heated so rapidly that is expands before any heat can escape, resulting in an absence of heat
aliya0001 [1]

Answer:

Adiabatic.

Explanation:

Any process in which there is no heat tranference is called adiabatic. In the situation, it is explained that due to the change of volume there is no heat between the gas and the environment.

Two blocks of masses 3.0 kg and 5.0 kg are connected by a spring and rest on a frictionless surface. They are given velocities t
miskamm [114]

Answer:

-0.7 m/sec

Explanation:

Mass of first block = m1 =3.0 kg

Mass of second block = m2= 5.0 kg

Velocity of first block = V1= 1.2 m/s

Velocity of second block = V2 = ?

Momentum of Center of mass MVcom  is sum of both blocks momentum and is given by

MVcom= m1v1+m2v2

Where

M= mass of center of mass

Vcom= Velocity of center of mass=0 m/s (because center of mass is at rest , so Vcom = 0 m.sec)

Putting values, we get;

0= 3×1.2+5v2

==> v2=  3.6/5= - 0.7 m/s

-ve sign indicates that block 2 is moving in opposite direction of block 1

The boiling point of water is 91.30 °C on the
Taya2010 [7]

Answer:

196.34 °F

Explanation:

To convert from degrees celsius to degrees fahrenheit, use this equation:

(°C * 9/5) + 32 = °F

So, using this equation:

(91.30 * 9/5) + 32 = °F

196.34 + 32 = °F

°F = 196.34

Hope this helps!
