Anika asks Eva to roll a basketball and then a bowling
Alex73 [517]

Answer:

the bowling ball, because it has more mass and  therefore more inertia

Explanation:

As per law of inertia we know that if an object is having more inertia then it is difficult to change state of motion.

Inertia is the property of mass of an object which always resist to change the state of motion of the object.

If an object has more inertia then it is more difficult to change the state of motion.

Now we know that we have one bowling ball and one basket ball, since bowling ball is having more mass then it must have more inertia so it is difficult to start the motion in bowling ball.

So correct answer will be

the bowling ball, because it has more mass and  therefore more inertia

Just about everyone at one time or another has been burned by hot water or steam. This problem compares the heat input to your s
kkurt [141]

Answer:

B. Steam burns the skin worse than hot water because the latent heat of vaporization is released as well.

Explanation:

It is given that both steam and the boiling water when in contact with the skin cools down from 100 to 34 degrees Celsius.

For any substance of mass m, the heat required to change the temperature by \Delta T is mC\Delta T (S.I. unit = Joules).

where C, the specific heat capacity is the same and a constant for both the condensed steam and the boiling water.  

But, there is a "hidden" energy (heat) released by the steam called latent heat

(given by mL, L = specific latent heat) which allows the phase transition (gas to liquid). While both of them are at the same temperature, their energy (heat) is different, which is why steam causes burns worse than boiling water

A block slides at constant speed down a ramp while acted on by three forces: its weight, the normal force, and kinetic friction.
Afina-wow [57]

Answer:

a) True

b)False

c)False

• Had to complete the question first.

A block slides at constant speed down a ramp while acted on by three forces: its weight, the normal force, and kinetic friction. Respond to each statement, true or false.

(a) The combined net work done by all three forces on the block equals zero.

(b) Each force does zero work on the block as it slides.

(c) Each force does negative work on the block as it slides.

Explanation:

Net work is the change in kinetic energy, which leads to final kinetic energy - our initial kinetic energy this is the formula for net work. This is the working energy theorem, a theorem that states that the net work on an object induces a change in the object's kinetic energy.
