Let's see

  • ∆T=58-50=8°C

So

\\ \rm\Rrightarrow Q=mc\Delta T

\\ \rm\Rrightarrow 4032=4200(8)m

\\ \rm\Rrightarrow 4032/8=4200m

\\ \rm\Rrightarrow 504=4200m

\\ \rm\Rrightarrow m=0.12kg

\\ \rm\Rrightarrow m=120g

Consider the following statements about Newton's 2nd law in general. Select all of the statements that are true. Note, there may
Art [367]

Answer:

1. True

2. False

3. True

Explanation:

Newton's 2nd law states that the net force exerted on an object is equal to the product between the mass of the object and its acceleration:

\sum F = ma (1)

where

\sum F is the net force on the object

m is its mass

a is the acceleration

Furthermore, we know that acceleration is defined as the rate of change of velocity:

a = \frac{dv}{dt}

So let's now analyize the three statements:

1. A net force causes velocity to change: TRUE. Net force (means non-zero) causes a non-zero acceleration, which means that the velocity of the object must change.

2. If an object has a velocity, then we can conclude that there is a net force on the object: FALSE. The fact that the object has a velocity does not imply anything about its acceleration: in fact, if its velocity is constant, then its acceleration is zero, which would mean that the net force on the object is zero. So this statement is not necessarly true.

3. Accelerations are caused by the presence of a net force: TRUE. This is directly implied by eq.(1): the presence of the net force results in the object having a non-zero acceleration.
