The kinetics formula that applies to this problem is
1. To find height, we use 1/2mv12−mg∗μ∗h sin θ = mgh where μ is equal to 0.20, v is 11 m/s and <span>θ is 40 degrees. we cancel mass, h is equal to 5.47 meters.
2. The final speed is from 2(ug</span>) * h sin <span>θ </span><span> = vf2
</span>2(0.2*9.8) * <span>sin 40 * 5.47= vf2 ; vf is equal to 3.71 m/s.
</span><span>

I believe that says that the car is going 125 meter per 5 seconds
Answer:
It's really important waves type for fulfill human's needs
Explanation:
Electromagnetic waves are transverse waves composed by the perpendicular oscillating electric and magnetic fields.
EM waves have both Electrical and magnetic features.
they travel in the velocity of light (3*10⁸ ms⁻¹)
they does not require any media to travel. It has two perpendicular electric field and the magnetic field which are perpendicular to each other
They travel perpendicular to each of those electric and magnetic fields.
Example :
- Radio Wave
- Micro Wave
- IR wave
- Light Wave
- UV rays
- X rays
- Gamma rays
- Cosmic rays
The main importance of em waves is they allow energy to be stored within them and then can be propagated over a large distance using the dielectric and magnetic properties of materials .
This performance has been used in many fields wisely and effectively to make the things easy.
Ex : medicine , Telecommunication , energy , Engineering etc
Answer:
It is located at the point where circles intersect on a map.
Explanation:
The name 'EPICENTER' was formed by a seismologist from Ireland can Robert Mallet.
An epicenter of an earthquake can be defined as the exact point in the center where as earthquake originated from.
An epicenter of an earthquake can also be defined as the point that is located directly above the focal point of an earthquake.
In other to be able to accurately determine the exact place where an earthquake happens, seismologist try to find out the distance of the earthquake from at least three seismic recording stations. The distance of the earthquake is obtained from a an equipment used by seismologist called seismograph. After obtaining the values if this distance, circles with the right radius are then drawn around each station. The point where the three circles meet or intersect shows us the earthquake's epicenter.
