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.
Answer:
The distance traveled is 44.45 m
Solution:
As per the question:
Average speed, 
Time, t = 1.6 s
Now, convert the average speed into m/s:
1 km = 1000 m
1 h = 
To calculate the distance traveled:
Now,
We know that:
Speed, 
Thus
I can't help if u don't write the full question
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
