Answer:
A = [m/s]
B = [m/s²]
Explanation:
Assuming that V has SI units of m/s, then A and BT must also have units of m/s.
A = [m/s]
BT = [m/s]
Since T has SI units of s:
B [s] = [m/s]
B = [m/s²]
Option A, B, C, D
Child on a swing, Pendulum, Bow and Arrow, Roller Coaster is mechanical energy being conserved
<u>Explanation:</u>
Mechanical energy is the total of kinetic and potential energy in a thing that is employed to do a job. A conservative force is a power like gravitation or a spring that “bends backward” energy that was conveyed by producing activity. The friction and other non conservative forces, nevertheless, conservation of mechanical energy is surely conserved.
When one stretches or contracts an elastic object, one does act fronting the spring force, and that task finishes up saved as elastic potential energy. Constantly shifting things up and down, producing variations in potential energy is termed as gravitational potential energy.
Here Child on a swing, Pendulum, Bow & Arrow, Roller Coaster in all there is the continuous conversion between gravitational/elastic potential energy and kinetic energy.
Answer:
B
Explanation:
the river is caused by weathering and erosion is the breaking down of rocks
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
In a closed system, energy in form of heat (work) can be exchanged but not matter.
The answer to your question is C.
