Explanation:
Answer:
2.8 N
Explanation:
Fp = 7.7 N
mA = 12.1 kg
mB = 7 kg
Let a be the acceleration and Fc be the contact force between A and B.
By the free body diagram, use Newton's second law
Fp - Fc = mA x a ..... (1)
Fc = mB x a ..... (2)
Adding both the equations
Fp = (mA + mB) x a
7.7 = (12.1 + 7) x a
a = 0.4 m/s^2
Substitute this value in equation (2), we get
Fc = 7 x 0.4 = 2.8 N
Thus, the contact force between the two blocks is 2.8 N.
Explanation:
A glow stick because when you crack it in the dark it turns into a light that works in the dark
Electric field between the plates of capacitor is given by
potential difference between the plates of capacitor is given by
so above two parameters will depend on the charge of capacitor
rest we know that capacitance of capacitor is given as
so it is independent of charge
so correct answer will be
<em>The electric field across the plates. </em>
<em>The potential across the plates.</em>
