Answer:
speed =wavelenght x frequency
v=4.5 x 10 to the -7 x 667=0.3 x 10 to the -4 m/s
speed= distance/time
time=distance/speed
t=4 x 10 to the 16/0.3 x 10 to the -4=13.33 x 10 to the 20 seconds
Explanation:
Answer:
a). 6 seconds
b). 12 seconds
c). 176.4 meters
Explanation:
a). Equation to be applied to calculate the time taken by the rocket to reach at the peak height,
v = u - gt
where v = final velocity
u = initial velocity = 58.8 m per sec
g = gravitational pull = 9.8 m per sec²
t = duration of the flight
At the peak height,
v = 0
Therefore, 0 = 58.8 - (9.8)(t)
t = 
= 6 seconds
b). Total time of flight = 2(Time taken to go up)
= 2×6
= 12 sec
c). Formula to get the peak height is,

h = (58.8)6 - 
= 352.8 - 176.4
= 176.4 meters
The correct answer is B .
Electrically charged particles.
Explanation:
Hey there!
Given;
Force (f) = 100 N
Acceleration (a) = 10m/s^2.
Mass (m)=?
We have;
Force = mass * acceleration.
So,
100 = m * 10
Or, 100 = 10m
Or, m= 100/10
Therefore, mass is 10kg.

Answer:
if the object is already moving and a force is applied in the same direction, the object will speed up or accelerate.
hope this helped :)
