The ball's horizontal component of velocity (ie it's horizontal speed) is 20 cos 40degrees. Without knowing the distance of the ball to the wall it's difficult to go further ...
a). (0.7 gal) x (231 in³/gal) x (1 meter / 39.37 in)³ =
= (0.7 x 231 x 1) / (39.37³) cubic meter
= 0.00265 cubic meter.
b). The volume of paint used to coat the wall is
V = (area of the wall) x (thickness of the paint) .
0.00265 m³ = (13 m²) x (thick)
Divide each side
by 13 m² : Thickness = 0.00265 m³ / 13 m²
= 0.000204 meter .
(0.204 millimeter)
(0.00802 inch)
Answer:
The acceleration is
Explanation:
Given that,
Speed
Time t = 60.0 sec
We need to calculate the acceleration
Using formula off acceleration
We know that,
Missile goes from rest
So, Initial velocity =0
Put the value into the formula
On right hand side multiplying and dividing by g = 9.8m/s²
Put the value of g
Hence, The acceleration is
Answer:
the two objects are in thermal equilibrium
Explanation:
thermal equilibrium us the state where two bodies or objects have the same amount of temperature thus no heat conduction
Each elements is made up only one atom. Atom is the basic unit of matter.
