Answer:
The distance between knothole and the paint ball is 0.483 m.
Explanation:
Given that,
Height = 4.0 m
Distance = 15 m
Speed = 50 m/s
The angle at which the forester aims his gun are,
Using the equation of motion of the trajectory
The horizontal displacement of the paint ball is
Using the equation of motion of the trajectory
The vertical displacement of the paint ball is
Put the value into the formula
We need to calculate the distance between knothole and the paint ball
Hence, The distance between knothole and the paint ball is 0.483 m.
B.) <span>Newton’s second law states that to increase acceleration, you "Increase Force"

Answer:
The radius of the circular plate is 0.774 m
Explanation:
Given;
distance between the parallel plates, d = 1.53 cm = 0.0153 m
electric field energy density between plates, = 4.41 J/m³
Potential energy of the capacitor, = 0.127 J
Energy density is given as;
where;
V is volume
Volume is given as;
V = Ad
where;
A is area
A = V / d
A = (0.0288) / (0.0153)
A = 1.882 m²
Area of circular plate is given as;
A = πr²
where;
r is the radius of the circular plate
Therefore, the radius of the circular plate is 0.774 m
Answer:
I think it is False.
Explanation:
I think that a body could not be vertical for every time.
A high-mass star has layers that are arranged in order of b. Temperature for fusion.
<h3>What is the temperature of fusion?</h3>
The temperature at which a substance transforms from a solid to a liquid is known as its melting point. The solid and liquid phases are in equilibrium at the melting point. Pressure affects a substance's melting point, which is typically reported at a standard pressure such 1 atmosphere or 100 kPa. There are two main categories of fusion reactions: those that maintain the ratio of protons to neutrons and those that convert protons to neutrons. The solid-liquid and liquid-to-gas transitions are connected with the typical heats of fusion and vaporization, respectively, for each substance.
