Answer:
The strength of the electric field is
.
Explanation:
Given that,
Speed 
Time 
Angle = 45°
We need to calculate the acceleration
Using equation of motion




We need to calculate the strength of the electric field
Using relation of newton's second law and electric force



Put the value into the formula


Hence, The strength of the electric field is
.
Answer:
making sure that you change one factor at a time while keeping all other conditions the same
Explanation:
Answer:
Food, wind, water.
Explanation:
This is supposed to be a personalized question so I answered with things that can make/give energy.
The upward force exerted on the board by the support is 530.8 N.
<h3>Upward force exerted on the board by the support</h3>
The sum of the upward forces is equal to sum of downward forces;
total downward forces = 52.8 N + 206 N + 272 N = 530.8 N
downward force = upward force = 530.8 N
Thus, the upward force exerted on the board by the support is 530.8 N.
