Yes because some people have more fat (insulation) on their bodies while some shave less. Also our bodies respond to temperature differently and some people are freezing while others think it’s hot.

A daring ranch hand sitting on a tree limb wishes to drop vertically onto a horse galloping under the tree. The constant speed o
barxatty [35]

Answer:

D = 7.82 m

Explanation:

given,

speed of horse = 10 m/s

vertical distance between the saddle and limb = 3 m

horizontal distance = ?

Calculation of time taken to cover the vertical distance.

using equation of motion

s = u t + \dfrac{1}{2}at^2

initial velocity = 0 m/s

s = 0+ \dfrac{1}{2}at^2

t = \sqrt{\dfrac{2s}{a}}

t = \sqrt{\dfrac{2\times 3}{9.8}}

t = 0.782 m

horizontal distance covered in this time

D = v t

D = 10 x 0.782

D = 7.82 m

Horizontal distance covered is equal to 7.82 m.

m_a_m_a [10]

If i measure the recession velocities of 2 galaxies and galaxy a has a velocity twice that of galaxy b, the far of b if a is 200 mpc away is   100 Mpc

<h3>Further explanation </h3>

The parsec (pc) is a unit of length used to measure the large distances to astronomical objects outside the Solar System.

Although parsecs are used for the shorter distances within the Milky Way, multiples of parsecs are also required for the larger scales in the universe such as Kiloparsecs (kpc) is for the more distant objects within and around the Milky Way, megaparsecs (Mpc) for mid-distance galaxies, and gigaparsecs (Gpc) for many quasars and the most distant galaxies.

If i measure the recession velocities of 2 galaxies and galaxy a has a velocity twice that of galaxy b, how far away is b if a is 200 mpc away? Remember that v = h_0 * d

galaxy A:  2(galaxy B's V) = H_0 * 200

galaxy B's V = H_0 * 100

galaxy B:  100 Mpc

A geyser shoots water straight up into the air with a velocity of 28.0 m/s. how
Fed [463]

The maximum height reached by the water  before it starts coming back down is 40 m.

<h3>Maximum height reached by the water</h3>

The maximum height reached by the water  before it starts coming back down is calculated by applying the principle of conservation of energy.

P.E = K.E

mgh = ¹/₂mv²

gh = ¹/₂v²

h = (v²)/(2g)

h = (28²)/(2 x 9.8)

h = 40 m
