Answer:
9.6 m/s
Explanation:
Angle of projection, θ = 28°
Horizontal distance, R = 7.8 m
Let the velocity of projection is given by u.
The formula used to find the velocity of projection is given by
u = 9.6 m/s
Thus, the velocity of projection is 9.6 m/s.
I would presume the factors would be soil and the sunlight. These two, I observe, are the needed factors for survival of the terrestrial organisms. And help them thrive.

Answer:
the answer might the number 2
Explanation:
None of these is a Physics problem. The numbers, and the fractions that
they appear in, might have come from Physics problems, but these are
nothing more than arithmetic exercises, and they can be whipped out
in a hurry with a little bit of fancy calculator work. You don't have to
know any Physics in order to answer any of these.
The first one is 2.7 x 10⁻²⁴ Newton.
Answer:
69.69 g
Explanation:
Evaporation of water will take out latent heat of vaporization. Let the mass of water be m and latent heat of vaporization of water be 2260000 J per kg
Heat taken up by evaporating water
= 2260000 x m J
Heat lost by body
= mass x specific heat of body x drop in temperature
60 x 3500 x .750 ( specific heat of human body is 3.5 kJ/kg.k)
= 157500 J
Heat loss = heat gain
2260000 m= 157500
m = .06969 kg
= 69.69 g
