Answer:
1. f=1T. where: f is the frequency of the wave in hertz. T is the period of the wave in seconds.
2. f=vλ where: f is the frequency of the wave in hertz. v is the velocity of the wave in meters per second. λ is the wavelength of the wave in meters
3. f=cλ
Explanation:
Tension in the rod is responsible for balancing force due to gravity.
<span>Since the trains area headed in completely opposite directions, the rate at which they gain distance from each other is simply equal to the sum of the magnitudes of their velocities, in this case 85 + 75 = 160 miles per hour. Therefore, the amount of time it will take for them to be 352 miles apart is 352/160 = 2.2 hours, or 2 hours and 12 minutes.</span>
The blue car is moving with a velocity of -14 m/s using the red car as a reference frame.
Answer:
Explanation:
Given:
time (t = 10.0 sec)
power = 150 Hp
We need to find the energy transformed by a 150 Hp engine in 10 s.
Solution:
First we convert 150 Hp in watt.
So, power (p = 111900 watt)
We know that, if we multiply power by time, we get energy transform by engine.
-----------(1)
Where:
P ⇒ power.
E ⇒ Energy.
t ⇒ time.
Substitute p = 111900 watt and t = 10 s in equation 1.
Therefore, a 150 Hp engine could transform 1,119,000 joules energy in 10 s.
