The product of a force and the perpendicular distance from the force's line of action to the axis of rotation is known as Torque.
Torque or moment of the force is the term used to describe a force's ability to turn.
The moment arm is the length that separates the line of action perpendicular to the axis of rotation. Torque is a mathematical combination of force F and moment arm L. Torque is equal to F times L. The moment arm affects torque. The torque will create more of an increase the longer the moment arm.
The line of action of a force is the path it travels when exerting its power.
The moment arm of the force is the length that separates the force's path of action from its axis of rotation perpendicularly.
The newton meter is the torque SI unit (Nm). A force of 1 N operating perpendicular to the moment arm's length of 1 m produces a torque of 1 N m.

what is the theoretical effect on the period when you change the revolving mass while keeping the radial force and radius the same?
Changing the revolving mass and keeping the radial force same the Period will alter. According to variations in revolving mass.
What is radial force?A force applied in a radial direction toward or away from the centre is referred to as a radial force. When a massed body or fluid element moves in a circular motion, an equilibrium between the centripetal force acting from the inside and the centrifugal force acting from the outside is created in the radial direction.
F = mv²/r
F = Force required to keep the mass in a circle
m = mass
v = velocity of the mass
r = radius of the circle.
Since, v = 2πr/t
Where t = period
π = pie
Substitute the value of v
We have, F = m(2πr/t)²/r
F = 4π²r²m/t²r
F = 4π²rm/t²
If the path radius and radial force are kept constant then mass is directly proportional to period
m ∝ t
Which means if mass increases period will increase as well.

you are testing a new car using crash test dummies. consider two ways to slow the car from 90 km/h (56 mi/h) to a complete stop: (i) you let the car slam into a wall, bringing it to a sudden stop. (ii) you let the car plow into a giant tub of gelatin so that it comes to a gradual halt. in which case is there a greater impulse of the net force on the car?
In a car crash test, whether you let the car slam the wall or let the car plow into a tub of gelatin, the impulses are the same. However, you and your car will experienced greater force if the car slam the wall.
The impulse is defined as the change in momentum.
I = Δp = m . Δv
Where:
I = impulse
p = momentum
m = mass
v = velocity / speed.
From the Newton's second law of motion:
m = F/a
Where:
F = force
a = acceleration
Hence,
I = F / a . Δv
I = F . Δv/a = F . t
Where t = time period of the exerted force.
The initial and the final velocities of the car are the same for both cases. Hence, from the definition of impulse as the change of momentum, the impulses on both cases are the same. However, if the car experienced sudden stop, which means the force exerted on it in only a very short time, the exerted force on the car will be very large.

How will this surfboard’s streamlined shape affect its speed?
Answer: Speed increases
Explanation:
A streamlined shape reduces the surface area making contact with the fluid (in this case, water). Less surface area making contact with the fluid means friction is reduced. The lower the force of friction, the lower the "drag" on the object in motion, hence the faster it can go. The force of friction is always in the opposite direction of the motion of the object.

why do massive stars collapse after they have fused silicon to make nickel, which then decays to make iron in their cores?
The sudden cessation of energy generation causes the core to collapse and the star's outer layers to collapse onto the core.
What is core collapse?
Core-collapse supernovae are spectacular explosions that occur at the end of a big star's thermonuclear evolution, giving rise to neutron stars and black holes. They are among the most intense occurrences in the universe, play an important role in the synthesis and distribution of chemical elements, drive the development of new stars, and are closely tied to an enigmatic subclass of gamma-ray bursts. As a result, astro-physicists are keen to learn which stars burst as supernovae, what physical mechanisms produce the explosion, and what observable effects result from these cataclysmic events.
When the explosion wave generated in the optically obscured stellar centre eventually reaches the surface layers of the star, the visual supernova outburst begins.
The fire ceases because iron does not work as a fuel. The sudden cessation of energy output leads the core to collapse and the star's outer layers to collapse onto the core. The infalling layers compress so quickly that they 'bounce' off the iron core at near-lightspeed.

A 90.0 gram mass is 75 centimeters from the pivot point on a balance scale. What mass must be placed 45
centimeters from the pivot to create rotational equilibrium?
Answer:
Explanation:
Given:
m₁ = 90.0 gram = 0.090 kg
L₁ = 75 cm = 0.75 m
L₂ = 45 cm = 0.45 m
__________________
m₂ - ?
Lever balance (rule of moments):
M₁ = M₂
F₁·L₁ = F₂·L₂
m₁·g·L₁ = m₂·g·L₂
m₁·L₁ = m₂·L₂
Mass:
m₂ = m₁·L₁ / L₂
m₂ = 0.090·0.75 / 0.45 = 0.150 kg or 150 gram
a hydrogen balloon rises up when released. within a short period of time, the balloon expands and does a work of 6000 j to the outside environment. during the same period of time, it also loses 12000 j of heat. how much does the internal energy of the balloon changes?
It's internal energy decreases of 18000J.
ΔQ = ΔU + ΔW
-12000J = ΔU + 6000
ΔU = - 18000J
Internal energy is the energy attributed to the disorderly, haphazard motion of molecules. It refers to the intangible microscopic energy on the atomic and molecular levels, which is distinct in scale from the macroscopic organised energy connected to moving objects. A glass of water that is at normal temperature and is resting on a table, for instance, has no discernible potential or kinetic energy. Although it is a seething mass of molecules moving at hundreds of metres per second at the microscopic level. When we superimpose an ordered big scale motion on the water as a whole, this tiny energy would not necessarily alter if the water were thrown across the room.
