Answer:
The correct solution is "14.6875 kg".
Explanation:
Given values:
Force,
F = 47.0 N
Acceleration,
a = 3.20 m/s²
Now,
⇒ 
or,
⇒ 
⇒ 
⇒ 
⇒ 
1 Electrical Potential Energy, separating two charged plates will store energy as the plates want to return to their original position.
<span>2 Spring or Elastic can be stretched to store energy as it wants to return to rest </span>
<span>3 Gravitational energy is stored by moving something (ball or pendulum are both examples of this) against a gravity gradient (lifting an object) that wants to fall back down. </span>
Answer:
The earth rotates from West to east
Explanation:
- Every planet in our solar system rotates around their axis in West to east direction.
- Only Venus is the only planet which rotates from east to west
FORMULA:
- V = IR, where V = P.D; I = Current; R = Resistance.
ANSWER:
Total equivalent resistance for circuit:
R(eq) = R1 + R2 [It is in series]
Now, Current passing through whole circuit:
I = V/R
We know that, In series combination current passing through whole circuit is same.
So, V¹ = IR¹
V¹ = 1/50 × 330
And V² = IR²
V² = 1/50 × 470
The total mass of the galaxy is 443.4 Solar mass
Orbital velocity (
) = 
where M= weight of galaxy
G= gravitational constatnt = 
(given)
R = distance from centre = 
Light years (given)= 
km (1 ly= 
billion km)
v= orbital velocity = 
(given)
∴ According to the formula
= 
⇒ 
(cross multiplying and expanding)
⇒ 
⇒ 
⇒ 
1 solar mass = 
⇒ Mass in solar mass =443.4 Solar mass
⇒ M = 443.4 Solar mass
