Answer:
0.5 m/s2
Explanation:
Step 1:
Data obtained from the question.
Total Mass = 60Kg
Net force = 30N
Acceleration =?
Step 2
Determination of the acceleration.
Force = Mass x Acceleration.
With the above equation, we can easily obtain the acceleration as follow:
30 = 60 x Acceleration
Divide both side by 60
Acceleration = 30/60
Acceleration = 0.5 m/s2
Now, we can thus say that the acceleration at that moment is 0.5 m/s2

I think deposition of C is the oldest deposit
Explanation:
Gauss Law relates the distribution of electric charge to the resulting electric field.
Applying Gauss's Law,
EA = Q / ε₀
Where:
E is the magnitude of the electric field,
A is the cross-sectional area of the conducting sphere,
Q is the positive charge
ε₀ is the permittivity
We be considering cases for the specified regions.
<u>Case 1</u>: When r < R
The electric field is zero, since the enclosed charge is equal to zero
E(r) = 0
<u>Case 2</u>: When R < r < 2R
The enclosed charge equals to Q, then the electric field equals;
E(4πr²) = Q / ε₀
E = Q / 4πε₀r²
E = KQ /r²
Constant K = 1 / 4πε₀ = 9.0 × 10⁹ Nm²/C²
<u>Case 3</u>: When r > 2R
The enclosed charge equals to Q, then the electric field equals;
E(4πr²) = 2Q / ε₀
E = 2Q / 4πε₀r²
E = 2KQ /r²
(B) 1.00 m
Explanation:
Since the meter stick is traveling with Jill, it will have the same speed as she does so relative to Jill, the meter stick is stationary so its length remains 1.00 m as measured by her.
