Answer:

FALSE

Explanation:

Monitoring heart rate is important in all physical activities. Some heart problems are silent and may manifest during increased physical effort, albeit moderate. Therefore, the practice of exercises should be authorized by a cardiologist and you should monitor your heart rate whenever possible. This is a simple matter now, as there are applications and wristbands that measure heart rate.

Two planets X and Y travel counterclockwise in circular orbits about a star, as seen in the figure.

sergeinik [125]

Planet Y has rotated by 135.5° through during this time.

To find the answer, we need to know about the relation between angle and radius of orbit.

<h3>What's the expression of angle in terms of radius?</h3>

Angle= arc/radius
As arc = orbital velocity × time,

angle= (orbital velocity × time)/radius

Orbital velocity= √(GM/radius), G= gravitational constant and M = mass of sun
So, angle = (√(GM)× time)/radius^3/2

<h3>What's is the angle rotated by planet Y after 5 years, if ratio of the radius of orbit of planet X and Y is 4:3 and planet X is rotated by 88°?</h3>

Let Ф₁= angle rotated by planet Y, Ф₂= angle rotated by planet X
As time = 5 years ( a constant)
Ф₁/Ф₂= (radius of planet X / radius of planet Y)^(3/2)
Ф₁= (radius of planet X / radius of planet Y)^(3/2) × Ф₂

= (4/3)^(3/2) × 88°

= 135.5°

Thus, we can conclude that Planet Y has rotated by 135.5° through during this time.

A quantity of gas has a volume of 0.20 cubic meter and an absolute temperature of 333 degrees kelvin. When the temperature of th

Nesterboy [21]

Answer:

Option C is the correct answer.

Explanation:

By Charles's law we have

V ∝ T

That is

$\frac{V_1}{T_1}=\frac{V_2}{T_2}$

Here given that

V₁ = 0.20 cubic meter

T₁ = 333 K

T₂ = 533 K

Substituting

$\frac{V_1}{T_1}=\frac{V_2}{T_2}\\\\\frac{0.20}{333}=\frac{V_2}{533}\\\\V_2=\frac{0.20}{333}\times 533=0.3198m^3$

New volume of the gas = 0.3198 m³

Option C is the correct answer.
