I think the correct answer form the choices listed above is option C. <span>The transfer of energy from objects with higher temperatures to objects with lower temperatures is defined as gradient transfer. If there are difference in temperature from one point and another point, then a gradient is present and heat transfer will surely happen.</span>
Answer:
w = 1.766 Joule
Explanation:
Work = Force × Distance
In this case the Work done is stored in body as Gravitational potential energy, so , W = P. E. = mgh
Here m = 0.400 kg ( unit not given in the question if in other unit may be converted to Kg), g = 9.81 m/s² and h= 0.450 m
w = 0.400 kg × 9.81 m/s² × 0.450 m
w = 1.7658 kg m²/s² = 1.766 Joule or (Nm)
Answer:
6 light years = 57 million km
Explanation:
Given;
A light year = 9.5 million km
To calculate how far is 6 light years;
6 light years = 6 × 1 light year = 6 × 9.5 million km
6 light years = 57 million km
