As a 2-kg ball rolls down a ramp, the net force on it is 10 N. What is the acceleration?

Answers

Answer 1

Answer: That all depends on the direction of the force. If the force is parallel to the ramp, then the acceleration of the ball is 5 m/s^2. If the force isn't parallel to the ramp, then the acceleration is less.

You and a friend ride bicycles to school. Both of you start at the same instant from your house, you riding at 13 m/s and your friend riding at 18 m/s . During the trip your friend has a flat tire that takes him 13 min to fix. He then continues the trip at the same speed of 18 m/s . If the distance to school is 13 km , which of you gets to school first? By comparing the total journey time for you and your friend, this question can be answered.
A student releases a block of mass m at the top of a slide of height h1. the block moves down the slide and off the end of the table of height h2, landing on the floor a horizontal distance d from the edge of the table. Friction and air resistance are negligible. The overall height H of the setup is determined by the height of the room. Therefore, if h1 is increased, h2 must decrease by the same amount so that the sum h1+h2 remains equal to H. The student wants to adjust h1 and h2 to make d as large as possible.A) 1) Without using equations, explain why making h1 very small would cause d to be small, even though h2 would be very large?2) Without using equations, explain why making h2 very small would cause d to be small, even thoughh1 would be largeB) Derive an equation for d in terms of h1, h2, m, and physical constants as appropriate.

How could you compare the energy carried in two different longitudinal waves

Answers

U could compare them using the intensity technique when bending waves are negligible in comparison with quasi-longitudinal waves.

Energy carried in two ways can be campared by using the intensity technique when bending waves are negligible in comparison with quasi-longitudinal waves.

What is the rms Voltage value and why we use it ?

Answers

Suppose that you have an alternating current generator. If you want to get the same result with a direct current (DC) generator, you have to set the voltage to the RMS (Root Mean Square) value of the (AC). In short, RMS is the value of the direct current voltage that is used instead of an alternating current.

The death of a star occurs when its _____ stops.nuclear fusion
nebular clouds
stellar gravity
rotation

Answers

Nuclear fusion
Stars fuse hydrogen into helium (and depending, also carbon, oxygen, neon, magnesium, silicon, and iron but that's complicated) to resist the force of immense gravity, in order to retain its shape.

the answer is: Nuclear fusion

What measures the distance between two consecutive crests of a wave?

Answers

The distance between two successive crests or two successive troughs is the wavelength for a transverse wave. The height of the crest from the undisturbed water position or the depth of the trough from the undisturbed water position is the amplitude of the wave.
