Answer:
120 km/s
Explanation:
Given data :
Radius of the star is r = 19 km
Rotational time period of the star is T = 1 s
Therefore, we know that the velocity of the star is given by :
V = 119380.52 m/s
Therefore, the velocity of the point on the equator of the star is = 120 km/s
Answer:
a.96cm
b.77cm
Explanation:
Highest intensity,=19cm
Lowest intensity,=29cm
48cm is the distance for half-wave, wavelength =48cm*2=96cm
b. From a, above we know that half-wavelength is 48cm
Also, the distance of known maximum is 29cm
Next maximum is calculated as:
The next maximum will occur at 77cm
Answer:
A. Muscular endurance
Explanation:
Muscular endurance is measured by the amount of time a muscle group can sustain a contraction.
Is that a question out of curiosity?
