1. The formula for momentum is:
p = mv
p =75(18) = 1350 kg-m/s
2. We equate the momentum of the two objects
0.25 v = 0.05 (500)
v = 100 m/s
3. We use the formula for impulse:
Δmv = FΔt
55(20) = F(0.5)
F = 2200 N
Formula for potential energy is:
pe = m * g * h
Where:
m = mass of an object
g = gravitational acceleration
h = height at which object is placed
From this equation we can make conclusion that increasing mass also increases potential energy. Object b has double the mass so it has double the potential energy.
Object a:
pe = m * 9.81 * 1
pe = 9.81 J
Object b:
pe = 2m * 9.81 * 1
pe = 19.62 J
Quartz, gold and calcite are examples of minerals, coal is a fossil fuel
Two examples of mutagens would be radiation mutagens and chemical mutagens. Hope this helps!
Use this formula to find your answer...
Determine the frequency of a clock waveform whose period is 2us or (micro) and 0.75ms
frequency (f)=1/( Time period).
Frequency of 2 us clock =1/2*10^-6 =10^6/2 =500000Hz =500 kHz.
Frequency of 0..75ms clock =1/0.75*10^-3 =10^3/0.75 =1333.33Hz =1.33kHz.
