Explanation:
(1). Formula to calculate the potential difference is as follows.
= 
= 
= 
= 
= 38.7 volts
Therefore, magnitude of the potential difference between the two spheres is 38.7 volts.
(2). Now, formula to calculate the energy stored in the capacitor is as follows.
E = 
= 
= 
Thus, the electric-field energy stored in the capacitor is
.
Answer:
A)Object 1 has the greater magnitude of its momentum.
B)The objects 2 have the greater kinetic energy.
Explanation:
For object 1 :
v₁ = v ,m₁ = 2 m
For object 2 :
,m₂=m
We know that linear momentum given as
P = M V
M=Mass , V=Velocity
For object 1 :
P₁ =m₁ v₁
P₁ =2 m v
For object 2


We can say that object 1 have more momentum.
The kinetic energy






Therefore both the object 2 have higher kinetic energy.
The electrical energy consumed by a toaster is 0.033 Kwh.
<u>Explanation</u>:
The power utilized by the toaster is 400 W.

The toaster is operated for 5 Minutes.

We know that,

Substitute the values in the above formula to obtain electrical energy,

Electrical energy = 0.4 × 0.083
Electrical energy is 0.033 Kwh.
Answer:
No.
Explanation:
Hot spots don't appear at the barriers of tectonic plates, instead, they originate at hot centres known as mantle plumes. Mantle plumes exist below the tectonic plates and may develop a string of volcanoes on the Earths surface.
