Answer:
30 C
Explanation:
Given:
Current flowing in the circuit (I) = 50 A
Start-up time (t) = 0.60 s
Now, we know that, charge drawn in through a cross sectional area of the circuit is given as:
Where, 'q' is the amount of charge drawn, 'I' is the current and 't' is the start-up time.
Now, plug in 50 A for 'I', 0.60 s for 't' and solve for 'q'. This gives,
Therefore, the amount of charge drawn in the circuit at the start-up of the compressor of an air conditioner is 30 C.
When the mass of the cart changes, the time to travel at 4.6 m/s is 28.11 s.
<h3>
Acceleration of the mule</h3>
The acceleration of mule is calculated as follows;
a = v/t
a = 5/10
a = 0.5 m/s²
<h3>For constant applied force</h3>
F1 = F2
m₁v₁/t₁ = m₂v₂/t₂
(180 x 5) / 10 = (550 x 4.6)/t
90 = 2530/t
t = 2530/90
t = 28.11 s
Thus, when the mass of the cart changes, the time to travel at 4.6 m/s is 28.11 s.

a) Proton-proton: high repulsive electrostatic, very high attractive nuclear force. Proton-neutron: no electrostatic forces since neutrons are not charge carriers, high attractive nuclear force. Neutron-neutron: no electrostatic force for the same reason and huge attractive nuclear force.
b) There are two types of forces in the nuclei: repulsive electrostatic and attractive nuclear. Nuclear act between all nucleons, electrostatic only between protons. To make a nucleus stronger, increase number of attractive forces by increasing amount of neutrons.
c) Cause due to equivalence between mass and energy E=mc^2 change in energy (which happens in nuclear reaction) causes on change in mass. Starting mass just converts to energy, that's why it's greater than the ending mass.
