True because friction happens when two things are rubbed against each other and it creates force and sliding something vigorously against something else can create force.
Answer:
a = 2 m/s²
Explanation:
average acceleration = change of velocity / change of time
a = Δv/Δt = (20 - 10) / 5 = 10/5 = 2
Answer:
43.96 L
Explanation:
We are given that
We know that
Substitute the values
Hence, the volume of balloon at -14.8 degree Celsius=43.96 L
The answer would be a reflection. This is because, t<span>he color of an object is actually the wavelengths of the light reflected while all other wavelengths are absorbed. Color, in this case, refers to the different wavelengths of light in the </span>visible light spectrum<span>perceived by our eyes. The physical and chemical composition of matter determines which wavelength (or color) is reflected.</span>
Answer:
31302 Volts and 55/111 Amps (≈0.5)
Explanation:
Secondary voltage / 141 = 1110 / 5
Secondary voltage = (1110*141) / 5
Secondary voltage = 31302
Amperage = 110/ (31302/141) = 55/111
