Answer:

0.7 amps

Explanation:

<u><em>Assuming that resistance is in ohms units:</em></u>

Current = Voltage / resistance

             = 70 / 100

             = 0.7 amps

A car travelling at 20 m/s due north along the highway makes a right turn on to a side road that heads due east. It takes 50 s f
Marrrta [24]

Answer:  initial velocity: 20 m/s

                time taken to complete the turn: 50s

               final velocity: 15 m/s

average acceleration= final velocity-initial velocity/time taken - 0s( 0 is taken here as there was no initial time)

           = 15-20/50-0

           = -5/50= -0.1 ms^2

A passenger on a stopped bus notices that rain is falling vertically just outside the window. When the bus moves with constant v
nekit [7.7K]

Answer:

1)0.325

2)6.17\ \rm m/s

Explanation:

<u>Given:</u>

The angle that falling raindrops make with the vertical=18^\circ

Let V_R be the velocity of the raindrops and V_B be the velocity of the bus.

1)

\dfrac{V_R}{V_B}=\tan 18^\circ\\\dfrac{V_R}{V_B}=0.315\\

2)Speed of the raindrops=0.315\times 19

=6.17\ \rm m/s

A ball thrown by Ginger is moving upward through the air. Diagram A shows a box with a downward arrow. Diagram B shows a box wit
vichka [17]

As the ball is moving in air as well as we have to neglect the friction force on it

So we can say that ball is having only one force on it that is gravitational force

So the force on the ball must have to be represented by gravitational force and that must be vertically downwards

So the correct FBD will contain only one force and that force must be vertically downwards

So here correct answer must be

<em>Diagram A shows a box with a downward arrow. </em>
