Electric current is the movement of electrons through a wire. Electric current is measured in amperes (amps) and refers to the number of charges that move through the wire per second.
4.285714268m/s/s is the answer
change in velocity divided by time equals acceleration
Answer:
maximum acceleration will be
Explanation:
We have given that mass of the box m = 29 kg
Coefficient of static friction
Acceleration due to gravity
For maximum acceleration
So acceleration will be
So maximum acceleration will be
Answer:
27.5Ω
Explanation:
Given parameters:
Potential difference in the circuit = 11V
Current in the circuit = 0.4A
Unknown:
Resistance in the circuit = ?
Solution:
According to ohm's law;
V = IR
V is the voltage
I is the current
R is the resistance
Since the unknown is R, we find it;
11 = 0.4 x R
R = = 27.5Ω
