pushups strain the mucles in your arms and chest.
after the exercise, they might be sore. that's because they are damaged and need to heal. when they heal, they will be stronger and more durable

When a planet is at its slowest orbital speed, its radius vector sweeps an area, A, in 45 days. What area will the radius vector

MArishka [77]

The area the radius vector will sweep is 0.889A

According to Kepler's second law, the radius vector sweeps out equal areas in equal times.

Let A = area and t = time period,

According to Kepler's law, A/t = constant

So, A₁/t₁ = A₂/t₂ where A₁ = area the radius vector sweeps at slowest orbital speed = A, t₁ = time period at slowest orbital speed = 45 days, A₂ = area the radius vector sweeps at fastest orbital speed, t₂ = time period at fastest orbital speed = 40 days.

Making A₂ subject of the formula, we have

A₂ = A₁t₂/t₁

Substituting the values of the variables into the equation, we have

A₂ = A₁t₂/t₁

A₂ = A × 40 days/45 days

A₂ = A × 40/45

A₂ = A × 8/9

A₂ = A × 0.889

A₂ = 0.889A

So, the area the radius vector will sweep is 0.889A

This is the number of complete movements of a wave per second.

Alona [7]

A unit for measuring frequency, equal to one cycle per second. If a sound wave has a frequency of 20,000 Hz, this means that 20,000 waves are passing through a given point during the interval of one second.

Plants depend on the atmosphere for the largest source of

Sonja [21]

The correct answer that would best complete the given statement above would be CARBON DIOXIDE (CO2). Plants depend on the atmosphere for the largest source of carbon dioxide. Carbon dioxide is considered as an important trace gas in the Earth's atmosphere which constitutes about 0.04% of it. Hope this answer helps.
