Answer:
<h2>4</h2>
Explanation:
Mechanical advantage is defined as the ratio of the load to the effort applied to raise the load. If minimal effort is used to overcome a much larger load, that is when we have what is called mechanical advantage i.e a machine has been used to our advantage.
Mathematically, MA = Load/Effort
Given parameters
Load = 160N
Effort = 40N
Required
Mechanical Advantage
Using the formula above
MA = 160N/40N
MA = 4
<em>advantage</em>
I think that the answer is A
E = I R
That means
Voltage = (current) x (resistance)
= (2.5 A) x (2.4 ohms)
= 6 volts .
Answer:
Electric field, E = 45833.33 N/C
Explanation:
Given that,
Separation between the plates, d = 4.8 mm = 0.0048 m
The potential difference between the plates, V = 220 volts
We need to find the electric field between two parallel plates. The relation between the electric field and electric potential is given by :
E = 45833.33 N/C
So, the electric field between two parallel plates is 45833.33 N/C. Hence, this is the required solution.
