Given, a = -3.2m/s²
v = 5m/s
t = 10s
u = ?
Using kinematic equation,
v = u + at
5 = u -3.2* 10
5 = u - 32
u = 32 + 5
u = 37 m/s
Answer:
They fell at the same time.
Explanation:
Galileo was the first to discover the property of gravity, in which it makes everything fall at the same time in an airtight space. Gravity makes all objects fall and accelerate at 9.8m/s/s, regardless of weight, because the ratio between the weight of the object and the air resistance acting against it is a constant.
surface wave is a wave that travels along the surface of a medium. The medium is the matter through which the wave travels. Ocean waves are the best-known examples of surface waves. They travel on the surface of the water between the ocean and the air.

Answer:
W
Explanation:
= Temperature of the room = 22.0 °C = 22 + 273 = 295 K
= Temperature of the skin = 33.0 °C = 33 + 273 = 306 K
= Surface area = 1.50 m²
= emissivity = 0.97
= Stefan's constant = 5.67 x 10⁻⁸ Wm⁻² K⁻⁴
Rate of heat transfer is given as
W
<>"Topographic maps conventionally show topography, or land contours, by means of contour lines. Contour lines are curves that connect contiguous points of the same altitude (isohypse). In other words, every point on the marked line of 100 m elevation is 100 m above mean sea level."<> I hope this helps.
