Answer:
A <u>scientific model</u> is a physical and/or mathematical and/or conceptual representation of a system of ideas, events or processes. Scientists seek to identify and understand patterns in our world by drawing on their scientific knowledge to offer explanations that enable the patterns to be predicted.
The gain in gravitational potential energy of the mass = 100 kg m^2 / s^2.
<u>Explanation:</u>
Gravitational potential energy is an energy in which an object possesses because of its position in a gravitational field. The most common use of gravitational potential energy is for an object near the Earth's surface where the gravitational acceleration can be assumed to be constant at about 9.8 m/s2.
The formula for the gravitational potential energy is the product of mass, gravity, and height.
GPE = m *g *h
where m represents mass in kg,
g represents the gravity,
h represents the height.
GPE = 5 * 10 * 2 = 100 kg m^2 / s^2.
U = I × R = 20A × 12 Ohm =240V
Answer:
5.865 μs
Explanation:
t₀ = Time taken to decay a muon = 2.20 μs
c = Speed of Light in vacuum = 3×10⁸ m/s
v = Velocity of muon = 0.927 c
t = Lifetime observed
Time dilation
∴Lifetime observed for muons approaching at 0.927 the speed of light is 5.865 μs
Shein. but i heard that kids work in a workshop and are forced to make the clothing. and i bought from them but i ddi not know and ya but thank you timmy for the t shirt
