Answer:

You are correct, it is (3) the ball is in motion as it rolls down the slope.

Explanation:

For number 1 it would make sense because how would the student be in motion if he is just standing there throwing the ball down the slope, not himself.

For number 2 still wouldn't make so much sense since we are talking about the ball being in motion not the student.

For number 3 it seems the most reasonable because the ball is in motion as it is rolling down the slope.

For number 4 it doesn't make sense for a ball to lose its shape just by rolling, also even if you're like: "oh, but what if its leaking air or has a hole??" well easy then. It STILL wouldn't matter because in the sentence it never specifies it has a "hole" or is "leaking air" therefore this answer is wrong.

YOUR ANSWER IS number 3.

A mass M is hanging from a rope of length L and mass m. A student gives the mass a quick horizontal shake to set up a wave which

disa [49]

Answer:

Explanation:

Expression for velocity of wave produced in a hanging wire can be given as follows

Velocity v = $\sqrt{\frac{T}{m} }$

where T is tension in wire and m is mass of wire per unit length.

In the given case

T = Mg + mg

= Mg

neglecting weight of rope

mass of the rope per unit length

= m / L

Velocity of wave

= $\sqrt{\frac{Mg}{\frac{m}{L} } }$

= $\sqrt{\frac{MgL}{m} }$

A wire of resistance R is cut into ten equal parts which are then connected in parallel. The equivalent resistance of the combin

Greeley [361]

Answer:

<em>The equivalent resistance of the combination is R/100</em>

Explanation:

<u>Electric Resistance</u>

The electric resistance of a wire is directly proportional to its length. If a wire of resistance R is cut into 10 equal parts, then each part has a resistance of R/10.

Parallel connection of resistances: If R1, R2, R3,...., Rn are connected in parallel, the equivalent resistance is calculated as follows:

$\displaystyle \frac{1}{R_e}=\frac{1}{R_1}+\frac{1}{R_2}+\frac{1}{R_3}+...+\frac{1}{R_n}$
