Abox is pulled up a rough ramp that makes an angle of 22 degrees with the horizontal surface. the surface of the ramp is the x-plane. what is the magnitude of the force of tension if the net force in the x direction of 98 n?
a.)57 n
b.)139 n 1
c.)78 n
d.)183 n
b 139

Explanation:

The balance of forces in the x-plane:

Where T is the force of tension and P is the wieght force

The weight in an inclined plane:

Where m is the mass of the box, g is the gravity force and a is the angle ( in this case 22°).

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
