Answer:
Explanation:
ACCORDING TO NEWTONS SECOND LAW;
F = mass * acceleration
F = m(v-u/t)
m is the mass = 0.15kg
v is the final velocity = 11m/s
u is the initial velocity = 0m/s
t is the time = 0.015
Substitute;
F = 0.15(11-0)/0.015
F = 0.15(11)/0.015
F = 1.65/0.015
F = 110N
Hence the net force is 110N
It would be Constructive interference. It occurs when two waves collide and make a taller wave.
C. is correct. when you make a pizza, you see the the meat or pepperoni or cheese heating up and sometimes melted. (thats physical). on the inside the crust in heated and the toppings are cooked (chemical)
Answer:10
Explanation:
You have to do speed divided by time so your answers 10
Answer:
344.8 Hz
Explanation:
The frequency of a wave is given by:
where
v is the speed of the wave
is its wavelength
Here we have
v = 793 m/s
Substituting into the equation, we find
