As per Newton's II law we know that
here
F = applied unbalanced force
m = mass of object
a = acceleration of object
now it is given that force F = 50 N North applied on block on earth due to which block will accelerate by 4 m/s^2
so here from above equation
Now we took another situation where block is placed on surface of moon and again force F = 25 N is applied on the block
So we will again use Newton's II law
so block will accelerate on moon by acceleration 2 m/s^2
Let's use the equations for rectilinear motion. One particular equation is:
d = v₀t +(1/2)at²
Since it has been mentioned that the object starts from rest, then v₀ = 0. Substituting the values,
40 m = (0)(4 s) + (1/2)(a)(4 s)²
Solving for a,
a = 5 m/s²
<em>Therefore, the acceleration due to gravity is 5 m/s².</em>
Answer:
Her bike is using kinetic energy
B
Explanation:
Answer : The average power delivered to the circuit is, 42.6 watt
Explanation :
The relation between power, voltage and current is:
where,
P = power of circuit = ?
I = current = 6.0 A
V = voltage = 7.1 V
Now put all the given values in the above formula, we get the average power delivered to the circuit.
Thus, the average power delivered to the circuit is, 42.6 watt
Remains the same. only by increasing the distance the electricity will flow do you increase the resistance, i.e, longer wire has more resistance than shorter wire.
