Answer:
I think d is the answer haha
Answer:
all areas of knowledge that wish to understand the physical, chemical and biological process must know electrostatics
Explanation:
Electrostatic interactions, have many rare manifestations in nature, which causes many reasons to study them.
- Lightning is a very striking form of electricity
- The biological processes are governed by currents of inanes and potential differences
- The transfer of nutrients and fertilizers to plants is with ion exchange, electrostatic forces
- all modern electronics is based on electricity
- the electric charge in very dry places, creates high currents that can create fires or kill people
In summary all areas of knowledge that wish to understand the physical, chemical and biological process must know electrostatics
1. Ideal Mechanical Advantage (IMA): 9
Explanation:
For a wheel and axle system like the steering wheel, the IMA is given by:
where
is the radius of the wheel
is the radius of the axle
For the steering wheel of the problem, we see that 
and 
, so the IMA is
2. Efficiency: 88.9%
Explanation:
The efficiency of a system is defined as the ratio between the AMA (actual mechanical advantage) and the IMA:
In this problem, AMA=8 and IMA=9, so the efficiency is
Answer:
Ah good question um no u dont have to be near it its a vr thing ur gonna have it on u the whole time. You can only be a few feet away from ur tv if u chose to do it on there or u can do it on ur phone but its also the same distance.

Answer:
Explanation:
Hooke's law is represented by thee formula
F = ke where F is force in N and K is the spring constant.
Initial length of the spring = 34cm = 0.34 m
mass of 7.00kg hung
weight = mg = 7 × 9.8 = 68.6 N
Final length of the spring = 44.5 cm = 0.445 m
extension = final length - initial length = 0.445 m - 0.34 m = 0.105 m
a) F = Ke
K = F / e = 68.6 N /0.105 m = 653.33 N/m = 0.653 kN/m
b) F = 150 N
k = 653.33 N/m
F = ke
150 N / 653.33 N/m = e
e = 0.23 m
new length = 0.34 + 0.23= 0.57 m = 57 cm
