Answer:
40 m/s
Explanation:
If you multiply the acceleration with time you get the average speed.
Answer:
Explanation:
Given
Original volume V1=30cm^3 converting to L
=30/1000=0.03L
Constant pressure P= 648 tors
Converting to atm; 648 tors*1atm/760 torr=0.853 atm
Work=984J= 984**1L/101.33=9.7L.atm
Note before
W= -P(Vfinal-Vinitial)
-9.7/0.853+0.03L=11.68L
Answer:
The moment of inertia of the bar is 
Explanation:
Given that,
mass of bar = 150 g
Length l = 36 cm
We need to calculate the moment of inertia of the bar
Using formula of moment inertia

Where,
M = mass of the bar
L = length of the bar
Put the value into the formula


Hence, The moment of inertia of the bar is 
The electric field is zero at x = -16.45cm
Data;
- q1 = 3.4 μC
- q2 = -2.0 μC
- distance = 5cm
<h3>The Electric Field at point 0</h3>
As the 3μC is larger than -2.0μC and the charges are opposite sign. The electric field will be zero at the negative axis.
Let the point be at x.
For an electric field to be equal to zero;

Let's solve for x using mathematical methods.

Solving the above quadratic equation;

The electric field is zero at x = -16.45cm
