Answer:

D is correct.

The upward force on the ball must be the same at both locations:

F = M a = 0 = F(upwards) - F(downwards)

If the ball is not being accelerated the upward force must equal the downward force on the ball.

In induction, what charge does a neutral substance gain compared to the object brought near it?
FromTheMoon [43]

Explanation:

In induction, what charge does a neutral substance gain compared to the object brought near it?

The neutral object gains the same type of charge as the object that touched it because the electrons move from one object to the other (Figure 10.16). Induction is the movement of electrons within a substance caused by a nearby charged object, without direct contact between the substance and the object.

If you are driving 100 km/h along a straight road and you look to the side for 1.6 s , how far do you travel during this inatten
denis23 [38]

Answer:

The distance traveled is 44.45 m

Solution:

As per the question:

Average speed, \bar{v} = 100\ km/h

Time, t = 1.6 s

Now, convert the average speed into m/s:

1 km = 1000 m

1 h = 60\times 60 = 3600\ s

To calculate the distance traveled:

Now,

100\ km/h = \frac{100\times 1000}{3600} = 27.78\ m/s

We know that:

Speed, \bar{v} = \frac{distance,\ d}{time,\ t}

Thus

d = \bar{v}t

d = 27.78\times 1.6 = 44.45\ m

A student is about to sled down a hill. He stands on a hill which is 30 meters tall and he weighs 40kg what is his GPE
PolarNik [594]

Answer:

11760J

Explanation:

Given parameters:

Height of hill  = 30m

Weight  = 40kg

Unknown:

Gravitational potential energy  = ?

Solution:

To find the gravitational potential energy, it is the energy due to the position of a body;

     G.PE  = mgh

m is the mass

g is the acceleration due to gravity

h is the height

 Now insert the parameters and solve;

      G.PE = 40 x 9.8 x 30  = 11760J
