Black holes of stellar mass are expected to form when very massive stars collapse at the end of their life cycle. After a black hole has formed, it can continue to grow by absorbing mass from its surroundings

When grip strength increases:
Nitella [24]

Answer:

e. the number of active motor units increases.

Explanation:

There is a direct relationship between the number of active motor units and the grip strength in a given scenario. <em>For example, increase in the grip strength leads to increase in the number of active motor units. In the other-hand, the decrease in grip strength leads to the decrease in the number of active motor units.</em>

At high pressures, what two factors will cause deviations during ideal gas law calculations?
Tju [1.3M]

At high pressures, the two factors that cause deviation during ideal gas law calculation are the size of molecular and intermolecular force.

The high pressure causes the molecules to approach each other at a very close distance. In that case, if the intermolecular force of attraction is high, the molecules may undergo a state transition, which will result in a completely different outcome as predicted by Ideal gas law.

If the size of the molecule is more, that is for heavy gases like refrigerants, the ideal gas law deviates due to the fact that, with increase in pressure, the volume of gas can no longer be considered as negligible.

In punting a football, the kicker tries to maximize both the distance of the kick and its "hang time"—the time that the ball is
Alex787 [66]

Answer:

v₀ = 26.17 m/s

Explanation:

If

R = Xmax = 50 yards = (50 yards)*(0.9144 m / 1 yard) = 45.72 m

t = 5 s  (Time of Flight)

we can apply the equation:

R = V₀x*t  ⇒   V₀x = R / t = 45.72 m / 5 s   ⇒   V₀x = 9.144 m/s

then we use the equation of Time of Flight:

t = 2*V₀y / g   ⇒    V₀y = g*t / 2 = (9.81 m/s²)*(5 s) / 2  ⇒    V₀y = 24.525 m/s

Finally we apply

v₀ = √(V₀x² + V₀y²)   ⇒   v₀ = √(9.144² + 24.525²) m/s

⇒   v₀ = 26.17 m/s
