Given parameters:
Mass of the body = 200g
Force on the body = 10N
Unknown parameters:
Acceleration produced by the force = ?
To solve this problem we must first define force in terms of mass and acceleration. This is possible due to the Newton's first law of motion.
Force = mass x acceleration
Here the unknown is acceleration and we can easily solve for it.
But we must take the mass to kilogram in order for it to cancel out.
1000g = 1 kg
200g = x kg = = 0.2kg
Now input the parameters and solve;
10 = 0.2 x acceleration
Acceleration = = 50m/s²
The acceleration produced by the body is 50m/s²
Answer:
Explanation:
Given that,
Current, I = 2 A
Voltage across the resistor, V = 18 V
We need to find the value of resistance of the resistor. Let the resistance be R. We can find it using Ohm's law i.e.
V = IR
Where
R is the resistance of the resistor
So, the resistance of the resistor is equal to .
