Answer: when shot scrapes off the top of the turf

Explanation: Divot is a term used in golf, where "Divot" is the piece of turf that is "cuted" out of the ground when the player tries to hit the ball.

Usually, the Iron or the Wedge are the ones that cause the divots, and while it may seem like a poor technique, it is actually pretty a common thing to see. At the point that in some cases, the divot itself is analyzed to see the technique of the player.

The correct option is the third one: "when shot scrapes off the top of the turf"

A torsion pendulum consists of an irregularly-shaped object of mass 20.0 kg suspended vertically by a wire of torsion constant 0

netineya [11]

Answer:

Rotational inertia of the object is, $I=0.023\ kg-m^2$

Explanation:

Given that,

Mass of the object, m = 20 kg

Torsion constant of the wire, K = 0.85 N-m

Number of cycles, n = 69

Time, t = 66 s

To find,

The rotational inertia of the object.

Solution,

There exists a relationship between the moment of inertia, time period and the torsion constant of the spring is given by :

$T=2\pi\sqrt{\dfrac{I}{K}}$

Here I is the moment of inertia

T is the time period, and it is equal to the number of cycles per unit time

$I=\dfrac{T^2K}{4\pi ^2}$

$I=\dfrac{(69/66)^2\times 0.85}{4\pi ^2}$

$I=0.023\ kg-m^2$

So, the rotational inertia of the object is $0.023\ kg-m^2$ .

To find the mass defect for uranium-238 several calculations must be made. Which is the calculation that should be made first? A

BaLLatris [955]

mass number of uranium 238 is sum of number of proton and neutrons in it

While atomic number is just number of protons

So total number of protons in it = 92

total number of neutrons in it = 238 - 92 = 146

mass of proton = 1.0073 amu

mass of neutron = 1.0087 amu

now for the calculation of mass of nuclei is given as

$M = zm_p + (A-z)m_n$

$M = 92(1.0073) + 146(1.0087)$

so option B is correct

In the photo, a locomotive has broken through the wall of a train station. During the collision, what can be said about the forc

Pavlova-9 [17]

Answer:

Whether the force exerted by the locomotive on the wall was larger

Than the force the locomotive could exert on the wall.

Explanation:

The Newton's third law of motion States that every force have it's equal and opposite reaction force, whose magnitude is the same as the applied force. Therefore the magnitude of these opposite forces will be equal.

So we have;

F12=-F21

F12 is the force in a direction

-F21 is the force in the opposite direction.

Therefore we see that the magnitude of the force the locomotive exerts on the wall is equal to the one the wall exerts on the locomotive. Both magnitudes are equal but in opposite directions.
