Density is mass per unit of volume. The density of argon is 1.778 × 10⁻³ gm/cm³.

Suppose that a finite amount of substance is there having its properties as:

Then, they are related as:

d = m/v

The volume of the tube = π × r² × h

                                = π × (2cm)² × 27.75 cm

                                = 348.716 cm³

Mass of Argon = Mass when tube is filled - Mass when tube is empty

                        = 188.87 g - 188.25 g

                        = 0.62 g

Now, the density of the gas can be written as,

Density = Mass / Volume

            = 0.62g / 348.716 cm³

            = 1.778 × 10⁻³ gm/cm³

Hence, the density of argon is 1.778 × 10⁻³ gm/cm³.

Answer : This is an example of Kenitic and potential energy

Explanation:

kenitic: the act of moving or motion

potential: not. moving YET

he was not moving when he was on the plane and had potential energy cause he wasn't getting pulled down and kenitic energy was when he was getting pulled down from force of gravity when he was getting pulled to the ground when he was skydiving

Answer:

39,200J

Explanation:

just took the test

The meteor's potential energy if it has a mass of 10kg at an altitude of 400 m will be 39200 J

Potential Energy that depend upon the relative position of various parts of system . It is an energy possessed by an object by virtue of its position or configuration.

mass(m)  = 10kg

g (acceleration due to gravity) = 9.8m/s^2

altitude(height (h)) = 400m

Meteor's Potential energy = m * g * h

                                           = 10 * 9.8 * 400 = 39200 J

correct option will be a) 39200 J

Answer:

1. 5 ft-lbs

2. 600 ft-lbs

The power of the first equation is 5 ft-lbs/sec and the power of the second equation is 10 ft-lbs/sec.

The power is a proportion of how rapidly work is being finished. It is the rate at which energy is moved or work is performed. The unit of force is watts (W), which is comparable to joules each second (J/s).

To compute power, we utilize the equation P = W/t, where P is power, W is work, and t is time. Work is how much energy moved when a power is applied over a distance, and it is estimated in foot-pounds (ft-lbs) or joules (J).

In the primary condition, the power is determined by partitioning 250 ft-lbs of work when it took to accomplish the work, which is 50 seconds. Thusly, the power is 5 ft-lbs/sec.

In the subsequent condition, we first proselyte 4 minutes to seconds, which is 240 seconds. Then, at that point, we partition 2400 ft-lbs of work by 240 seconds to get a force of 10 ft-lbs/sec.

The units for power are dependably ft-lbs/sec or J/s, and they address how much work done per unit time.

Answer:

a.) 490m

b.) 98m/s

Explanation:

Given that the

Acceleration g = 9.8 m/s^2

Time = 10s

Since the parachutist jumps out of an aeroplane. The parachutist jumped out from rest. Initial velocity U is therefore equal to zero. That is,

U = 0

Distance covered = height H

The height can be calculated by using second equation of motion

H = Ut + 1/2gt^2

Substitute g and t into the formula

H = 1/2 × 9.8 × 10^2

H = 490 m

Therefore, she travels as far as 490 m

b.) Her final velocity can be calculated by using third equation of motion

V^2 = U^2 + 2gH

Substitute g and H into the formula.

Remember that U = 0

V^2 = 2 × 9.8 × 490

V^2 = 9604

V = sqrt (9604)

V = 98 m/s

Therefore, her final velocity is 98 m/s
