Answer:

Explanation:

a. WEIGHT: As we have seen, weight is the gravitational force exerted on an object by the Earth (or any other celestial body). If an object is near the Earth's surface and has mass, then the object has a weight. The magnitude of its weight is w = mg and its direction is toward the center of the Earth.

How far (in meters) does a person travel in coming to a complete stop in 40 ms at a constant acceleration of 60g?
Nataly [62]

Answer:

d= 0.48 m

Explanation:

Given that

time ,t= 40 m s= 40 x 10⁻³ s

Constant acceleration ,a= - 60 g

We know that g= 10 m/s²

Therefore ,a=- 60 x 10 =- 600 m/s²

We know that

v= u + a t

u=initial speed

v=final sped

t=time

a=acceleration

Now by putting the value

0 = u - 600 x  40 x 10⁻³

u = 24  m/s

The distance cover before coming to stop d is given as

d=ut+\dfrac{1}{2}at^2

d=24\times 40\times 10^{-3}-\dfrac{1}{2}\times 600\times (40\times 10^{-3})^2

d= 0.48 m

If the volume of the balloon is 500 m3m3 and the surrounding air is at 15.0 ∘C∘C, what must the temperature of the air in the ba
Tresset [83]

Answer:

Temperature of the air in the balloon = 272°C

Explanation:

Given:

Volume of balloon = 500 m³

Air temperature = 15° C = 273 + 15 = 288 K

Total weight = 290 kg

Density of air = 1.23 kg/m³

Find:

Temperature of the air in the balloon

Computation:

Density of hot air = Density of air - [Total weight / Volume of balloon]

Density of hot air = 1.23 - [290 - 500]

Density of hot air = 0.65 kg/m³

[Density of hot air][Temperature of the air in the balloon] = [Density of air][Air temperature ]

Temperature of the air in the balloon = [(1.23)(288)]/(0.65)

Temperature of the air in the balloon = 544.98

Temperature of the air in the balloon = 545 K

Temperature of the air in the balloon = 545 - 273 = 272°C
