As you coast down a long hill on your bicycle, potential energy from your height is converted to kinetic energy as you and your bike are pulled downward by gravity along the slope of the hill. While there is air resistance and friction slowing you down by a little bit, your speed increases gradually until you apply the brakes, causing enough friction to slow yourself and the bike to a stop at the bottom
Answer:
The ax versus t graph stays in the range of 2.5 to 3 m/s2 for the first 2 seconds or so, and then it drops quickly to just below 0 m/s2. This corresponds well with the slope of the vx graph: relatively constant positive slope for the first 2.5 seconds, and then zero (and even negative) slope afterwards.
Explanation: Edmentum
Answer:
Explanation:
Parameters given;
Magnetic field intensity, B = 1.4 T
Speed of proton, v =
Mass of proton, m =
Charge of proton, q =
To find the acceleration of the proton, we first need to find the force exerted by the magnetic field on the proton:
F = q * v * B
F = * * 1.4
F =
This is the force exerted by the magnetic field on the proton. The force exerted by the proton has the same magnitude but an opposite direction as the force exerted by the magnetic field. Hence, = -
The force exerted by the proton is the product of its mass and acceleration. Hence, we can find its acceleration:
= ma
a = F/m
The magnitude, |a|, will be:
|a| =| |
|a| =
The magnitude of the acceleration of the proton is |a|
For the surface,i would say Most Likely Ignious rock,since the process happens from cooling and volcanoes are mostly found on the surface of the earth, Hope this helped (:
Answer:
85 K
Explanation:
T₀ = initial temperature of the gas = 77 K
T = final temperature of the gas = ?
n = number of moles of monoatomic gas = 1.00 mol
R = universal gas constant = 8.314
c = heat capacity at constant volume = (1.5) R = (1.5) (8.314) = 12.5
Q = Amount of heat absorbed = 100 J
Amount of heat absorbed is given as
Q = n c (T - T₀)
100 = (1) (12.5) (T - 77)
T = 85 K
