Answer:
Therefore, highest point that the cannon ball reaches is 168.7m
Explanation:
the cannon is fired at an angle 30 o to the horizonatal with a speed of 155 m/s
highest point that the cannon ball reaches?
g = 9.8m/s2
Therefore, highest point that the cannon ball reaches is 168.7m
Answer: sum of the electric field energy density and magnetic field energy density.
Explanation:
The total energy stored in an electromagnetic wave is equal to the sum of energy stored in the electric and magnetic fields. In that case, the energy stored per unit volume, or energy density of the electromagnetic wave, is the sum of the electric field energy density and magnetic field energy density.
Answer:
Explanation:
F = ma. For us, this looks like
60 = 30a and
a = 2 m/s/s
If the force goes up to, say, 90, then
90 = 30a and
a = 3...if the force goes up, the acceleration also goes up.
If the mass goes up to say, 60, and the force stays the same, then
60 = 60a and
a = 1...if the mass goes up, the acceleration goes down.
B. Is faster in solids than liquids would be the correct answer because the molecules in solids are much closer and can pass along energy faster and more effectively.
