Answer:
Option B, Fix the piston in place so the volume of the pas remains constant
Explanation:
As we know
The effect on variable due to another variable can be studied by keeping the third variable constant.
Hence, in order the study the variation of temperature with pressure or vice versa, the volume needs to fixed at a certain value.
Hence, option B is correct
Answer:
i think c
Explanation:
because cars run on mechanical energy and solar powered means its by the sun which is light energy
Given:
v = 50.0 m/s, the launch velocity
θ = 36.9°, the launch angle above the horizontal
Assume g = 9.8 m/s² and ignore air resistance.
The vertical component of the launch velocity is
Vy = (50 m/s)*sin(50°) = 30.02 m/s
The time, t, to reach maximum height is given by
(30.02 m/s) - (9.8 m/s²)*(t s) = 0
t = 3.0634 s
The time fo flight is 2*t = 6.1268 s
The horizontal velocity is
u = (50 m/s)cos(36.9°) = 39.9842 m/s
The horizontal distance traveled at time t is given in the table below.

Answer:
Afforestation is the planting or adding of trees in an area where there was never a forest or plantation. This is a method to create a new forest. Reforestation is the replanting of trees in an area where there was once a forest which was destroyed or damaged.

Answer:
Explanation:
Recall that the equation for the electric field intensity between the plates of a capacitor is given by:
where E is the electric field, 
is the voltage across the plate of the capacitor, and "d" is the separation (distance) between the capacitor's plates.
So we need to solve for the distance in the equation above, but also make sure that the units for electric field and potential difference are in agreement. We then write the electric field strength in V/cm :
1.1kV/cm = 1100 V/cm
Now in the equation:
