A solid disk of mass m and radius r undergoes an acceleration a The radius of the second disk is 4m.

The resistance of the body to acceleration (change of velocity) in the presence of a net force is also measured. The gravitational pull of an object to other bodies is also influenced by its mass.

The kilogramme serves as the mass basis unit in the SI (kg). In physics, mass is not the same as weight, despite the fact that weight is frequently measured using a spring scale as opposed to a balance scale and direct comparison with known masses to calculate mass. The lower gravity on the Moon causes an object to weigh less than it does on Earth, but it still has the same mass. Given that mass is a property of space rather than a force.

Answer:

8.2x10^2 Joules

Explanation:

Assuming that GPE means potential energy of the parachutist, and he/she is doing this on Earth, we can find their potential energy, (PE) with the equation:

PE  = mgh, where m is the mass of the parachutist in kilograms, g is the acceleration due to gravity [9.8 m/s2 for Earth (near surface)] and h is the height in meters.

m = 9.8 m/s^2

h = 12,000 meters (12 km)

m = 70 kg

PE = (70kg)(9.8 m/s^2)(12,000 m)

PE = 823,200 kg*m^2/s^2

PE = 8.2 x 10^2 kg*m^2/s^2

(1 kg*m^2/s^2) is the SI equivalent to a Joule.

Define distance?

Distance is a quantitative or qualitative measurement of the distance between two objects or places. Distance can refer to a physical length or an estimation based on other factors in physics or common use (e.g. "two counties over"). Because spatial cognition is a rich source of conceptual metaphors in human thought, the term is also used metaphorically to mean an estimation of the amount of difference between two similar objects (such as statistical distance between probability distributions or edit distance among strings of text) or a degree of separation (as exemplified by distance between people in a social network). The concept of a metric space is used to codify most such conceptions of distance, both physical and metaphorical.

Explanation:

F = ma

Let's consider m = 1 (the mass of the cart is not changing so it is constant),

F = 2, and a = 4.

2 = 1 x 4

When doubling force we need to maintain equality so acceleration should double too. To understand it better find the ratio of force and acceleration 2/4 = 1/2. The ratio of force to acceleration should always equal half in all scenarios, this way we can see how equality is maintained.

2x2 = 1 x (4x2)  

4 = 1 x 8, and the ratio of force to acceleration is 4/8 = 1/2.

Whtat is inelastic collision?

A collision in which a portion of the kinetic energy of the colliding particles is converted into another type of energy.

What is velocity?

The primary determinant of an object's position and rate of motion is its velocity. It can be explained as the distance an object travels in one unit of time. The object's displacement in a given amount of time is called velocity.

The velocity of block just before hitting the putty (by energy conservation)

K.Ei+P.Ei=K.Ef+P.Ef

⇒0+mgh=21mv2

⇒v=[tex]\sqrt{2}[/tex]gh

Let the common velocity of both block and putty be v'

At collision momentum balance:

mv=mv′+mv′

⇒[tex]\sqrt{2}[/tex]gh=2v′

⇒v′=[tex]\sqrt{g/h}[/tex]

Again applying energy conservation (both block and putty at max height)

K.Ei+P.Ei=K.Ef+P.Ef

⇒1/2 2mv²=2mgh′

⇒1/2 gh/2=gh′

⇒h′=h/4

Due to the distinctive design of our skeletal system, the range of motion is defined as the way our bodies move through space. especially how the bones adhere to one another at the joints. Because of each person's unique skeletal structure, every joint in the body has a defined range of motion. A joint's range of motion (ROM) refers to how far it can move actively or passively in a given direction. As opposed to passive ROM, which occurs when an external force moves the joint, active ROM occurs when muscles do so.

For mass movements, gravity is the primary driving force. A trigger is frequently present in mass-wasting occurrences.

It could be caused by human operations like grading a new road, quake shaking, super volcano, storm waves, or storm-related waves. Mass-wasting is most frequently caused by an increase in water content in the slope. Rapidly dissolving snow or ice, as well as a heavy downpour, can cause the water content to rise. The force of gravity pulls everything towards to the Earth’s centre from every point on its surface. Gravity pulls downward on a level surface that is also parallel to the surface of the Earth. The stability of the consolidated and poorly consolidated earth materials can be compromised by gravity, increasing moisture content, and seismic events.

Explanation:

The angular acceleration of the wheel is -20.25 rad/sec^2

Angular acceleration is defined as the rate of change of angular velocity over time.

so, α = 2*(θ  -  ωo t ) / t^2

angular velocity of the wheel = ωo  = 96.0 rad/sec

time taken by the wheel to rotate = t = 7 sec

angular distance travelled by the wheel  = θ 28 rev

As we know that,

In one revolution the wheel completes 360 degrees which is equals to  6.28319 rad

therefore angular distance traveled = 28 rev * 6.28319 rad

So, the angular acceleration = 2*(28*6.28 -  96*7) / 7^2 = -20.25 rad/sec^2

The wide wood pores that link to the tree's roots allow sap to be drawn up into the maple tree when it starts to freeze. The tree is really replenishing itself with fluids at this time from its roots.

As long as the temperature is below freezing and the sap is increasing, the process continues.

Water is drawn up from the roots to the top of the plant according to the cohesion-tension hypothesis of sap ascent. Water and minerals travel upward from the roots through the xylem due to a negative water potential gradient created by the evaporation of mesophyll cells in the leaves.

The water potential gets increasingly negative as you climb the tree, and these variations provide a pull or tension that causes the water to ascend the tree. The loss of water from the leaves through a process called transpiration is a crucial element in the draw of water up the tree.
