KE = 1/2 mv^2 is the relationship betwee mass and kinetic energy
In order for magma to form, wet or dry melting of rocks or minerals must occur. Dry melting occurs when minerals or rocks, with no carbon dioxide or water in them, are heated to a specific temperature.
Answer:
Covalent bonds can form between similar atoms.
Explanation:
Use SUVAT where:
S = distance
U = initial velocity = 30m/s
V = end velocity = 0 m/s
A = acceleration = ?
T = time = 5 secs
then pick out the equation v = u + at
so:
0 = 30 + 5a
-30 / 5 = a
a = -6 m/s^2
Answer:
2100 kg*m/s
Explanation:
The proper term for power in this case is to use the physics term "impuls" = p.
1. Find the "power" developed by the gun to fire just 1 bullet.
2. multiply by 60 to find the power produced by the gun per minute.
p = m * v
where
m = mass of the bullet = 50 g = 0.050 kg
v = velocity of the bullet = 700 m/s
p = 0.050 * 700
p = 35 kg*m/s
So the impuls for 1 bullet is 35 kg*m/s
The gun can fire 60 bullets per minute so it's fireing power must there fore be 60 * 35 = 2100 kg*m/s
