Explanation:
Physicists are scientist that studies physics. Physics is an aspect of physical science that seeks to understand the fundamental laws that governs how matter and energy interacts.
- Physics is a very broad science discipline and it uses the scientific method to investigate natural phenomenon.
- Applied physics deals with adapting physical solutions to provide technological solutions.
- Theoretical physics uses mathematical approaches to solve physics related problems.
- Experimental physics uses laboratory experiments for investigation.

Explanation:
I = 120/30=2A
Voltage across R3= current × resistance
= 2A × 15 ohm = 30 volt
We can find the force by using the following formula;
N = ma + mg
Fa = ma = 76 x 1.2 = 91.2
Fg = mg = 76 x 9.8 = 744.8
N = 91.2 + 744.8 = 836
So, the force is 836 N.
Answer:
<h2>0.39m/s^2</h2>
Explanation:
Step one:
given data
mass m= 300kg
applied force F= 1000N
coefficient of friction μ= 0.3
Step two:
The net force Fn= applied force-friction force
Fn=F-F1
F1= limiting force
F1=μ*m*g
F1=0.3*300*9.81
F1=882.9N
the Net force= 1000-882.9
Fn=117.1N
Step three:
we know that
F=ma
Fnet=ma
a= Fnet/m
a=117.1/300
a=0.39m/s^2
