I would say the correct answer is nighttime. The clouds in the atmosphere would absorb the radiation that is emitted by the Earth and at at night 30% of these would be radiated back to the Earth's surface. Hope this answers the question. <span />
Answer:
The velocity for the particle is (1i+2tj).
Explanation:
Given that,
The particle position is
...(I)
In form of x and y
....(II)
...(III)
From equation (II)

Put the value of t in equation (III)



We need to calculate the velocity
Velocity is the rate of change of the position of the particle


Hence, The velocity for the particle is (1i+2tj).
Answer:
<em>Potential energy , </em>because it is defined as <em>the energy</em> held by object because of its position relative to other objects.. It is based on its distance from ground
Given data
mass (m) = 67 kg ,
height (h) = 230 m ,
Potential energy (P.E.) = m. g. h
= 67 × 9.81 × 230
= 151172.1 J
P.E. = 151.18 KJ
The weight of any object is equal to the product of the mass of the object and the gravitational field strength of the environment.
Hence, weight = mass x gravitational field (mars)
weight = 55 x 3.7 = 203.5 N
Hope it helps. feel free to ask any doubts.
Answer:
<u>Displacement (km)</u>
Explanation:
The y axis is the vertical axis pointing up and down. This is labeled as the the displacement (km) in the graph.
