Answer:

The number of paces it would take to get to the Moon is 213,555,556 paces

Explanation:

The given length of Mr Galan's paces = 1.8 m/pace

The distance from the Earth to the Moon is, 384,400 km = 384,400,000 m

Therefore, the number of paces, "n", it would take to get to the Moon from the Earth is given as follows;

n = (The distance from the Earth to the Moon)/(The length of each Mr Galan's paces)

∴ n = 384,400,000 m/(1.8 m/pace) = 213,555,556 paces

The number of paces it would take to get to the Moon = n = 213,555,556 paces

K^+H^+G^=180° (sum of int angles of triangle)

K^+30+62=180

K^=88°

GH/sinK=KG/sinH

X/sin88=16/sin62

X*sin62/sin62=16*sin88/sin62

X=18.1

What is the RMS speed of Helium atoms when the temperature of the Helium gas is 206.0 K? (Possibly useful constants: the atomic

saw5 [17]

Answer:

a)1.13×10³

b)1.6×10³

Explanation:

Given:

Boltzmann's constant (K)=1.38×10^-23 J/K

atmoic mass of helium = 4 AMU or 4×1.66×10^-27kg

a)The formula for RMS speed (Vrms) is given as

$Vrms=\sqrt{\frac{3KT}{m} }$

where

K= Boltzmann's constant

T= temperature

m=mass of the gas

$Vrms=\sqrt{\frac{3\times 1.38\times 10^{-23}\times 206}{6.64\times 10^{-27}}}$

$Vrms=1.13\times 10^{3}m/s$

b) RMS speed of helium when the temperature is doubled

$Vrms=\sqrt{\frac{3\times 1.38\times 10^{-23}\times 2\times 206}{6.64\times 10^{-27}}}$

$Vrms=1.598\times 10^{3}m/s$

An athlete executing a long jump leaves the ground at a 28.0º angle and travels 7.80 m. (A) What was the takeoff speed?

Naddika [18.5K]

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

$R=\frac{u^{2}Sin2\theta }{g}$

$7.8=\frac{u^{2}Sin\left (2\times 28 \right ) }{9.8}$

$7.8=\frac{u^{2}\times 0.829}{9.8}$

u = 9.6 m/s

Thus, the velocity of projection is 9.6 m/s.

A person with a mass of 15kg is walking uphill at a velocity of2m/s. What is the walker's momentum?

Nadusha1986 [10]

Answer:

30 kgm/s

Explanation:

The momentum of a body is given by the product of mass and its velocity.

∴ momentum = mv

= 15 × 2

= 30 kgm/s
