The temperature of the box and floor eventually rise as a result of the thermal energy flowing as heat inside these two things.

This is further explained below.

Generally, The energy present in a system that determines its temperature is referred to as thermal energy.

Thermal energy flows as heat. Thermodynamics is a whole field of physics that studies how heat is transmitted across various systems and how work is performed in the process (see the first law of thermodynamics).

In conclusion, This thermal energy is transferred in the form of heat throughout the box as well as the floor, which eventually results in an increase in temperature for both of these locations.

Explanation:

What is acceleration ?

Acceleration is the rate at which the speed and direction of a moving object change over time. Something is said to be accelerating when it starts to move faster or slower

Let acceleration be a

For the hanging m, mg-T = ma

For the glider(mass M),T=Ma

Eliminating T,we get

mg-Ma=ma

a=mg/(m+M)

Using energy concept we will get the same result,

When m is lowered by h, M will move h distance in forward direction.

As there is no friction, both m and M will attain same speed (v).

So, mgh = 1/2(m+M)v2 [Word done by T will cancel out, as for m it is -hT while for M it is hT(see the direction of T and displacement in both cases)]

v2 =2mgh/(m+M)

Use formula v2 - u2 = 2as

Answer:

578.59235

Explanation:

59*9.8

9.8 is the force of gravity acting on the earth, therefore multiplying 59 and 9.8, you get 578.59N or, if you're rounding it up, 578.6N

The net force's work is described as d=(3.82)(4.00)=15.3J for W=F net, where we made use of the fact that the canister began at rest and traveled horizontally while being affected by horizontal forces; the resulting effect is represented by the symbol F net.

Since all of these cases are in closed systems, the result is in a new preserved quantity.

Linear momentum and this new quantity, angular momentum, are comparable. In this chapter, we first define angular momentum and then examine it from a number of angles.

But first, we look into a single particle's angular momentum. This enables us to compute the force angular momentum of a rigid cylindrically symmetric body and a system of particles.

We used the fact that the canister started at rest and moved horizontally under the influence of horizontal forces; the ensuing effect is denoted by the symbol F (force) net.

Its edges are subjected to a force of 2.8 x 1010 N at the specified shear stress and area.

The force known as shear stress is the tendency for a material to deform by slippage along a plane or planes parallel to the applied stress. Shear stress or pressures, as their name suggests, tend to "shear" objects or produce material deformation.

The formula for shear stress is given as:

F = Aτ

where;

F is the force applied, A is the area of the surface, and τ is the shear stress

We have,

Shear modulus, τ = 3.5 × 10¹⁰ Pa

The area of the plate is A = 0.8 m²

Then,

F = ( 0.8 m² ) × (3.5 × 10¹⁰ Pa)

F = 2.8 x 10¹⁰ N

As a result, as the shear stress grows, so does the force applied to each of its edges that causes the specified displacement.

The time shown by the speedometer corresponding to speed of 10 m/s is 1 s.

The time shown by the speedometer corresponding to speed of 20 m/s is 1 s.

The time shown by the speedometer corresponding to speed of 30 m/s is 1 s.

1. As shown by the speedometer on the right.

The speed of 10 m/s indicated by the speedometer to the right may be used to calculate how long the ball has been falling from the maximum altitude it reached.

Equation for free fall: Vf = Vo - gt

Vo=0, Vf=gt, and t=Vf/g

I suggest using an approximation of g for this problem: g = 10 m/s2 (I'll explain why in a moment).

1 second is equal to [10 m/s]/[10 m/s2].

The time is now dropping. From it has been four seconds since launch, the upward time was three seconds. You may use this to determine the launching speed.

2. The moment the speedometer registers 20 m/s

Determine the launching speed first:

Vo - gt = Vf

Given that the ball took 3 seconds to ascend and that its speed was zero at its highest point, you may calculate:

0 = Vo - gt

Vo=gt=10 m/s2 3 s = 30 m/s

Now, while the ball is moving upward and the speedometer reads 20 m/s, use the beginning velocity to compute.

t = [30 m/s - 20 m/s] / [10 m/s2] = 1 s 20 m/s = 30 m/s - 10 m/s2

Therefore, t = 1 s is the initial solution.

3. The moment the speedometer registers 30 m/s.

The projected speed for the launch is also 30 m/s.

This reading therefore reflects the precise moment the ball was released.

Time is therefore 0 and the launch moment remains the same.

Answer:

If the resistors are in series then each resistor

carries the "same current" - the first option

Recall, Newton's gravitational law states that any particle of matter in the universe attracts any other particle with a force varying directly as the product of their masses and inversely as the square of the distance between them. It is expressed as

F = Gm1m2/r^2

where

F is the force in Newton

G is gravitational constant = 6.673 x 10^-11 Nm^2/kg^2

m1 and m2 are the masses in kg

r is the distance in meters

From the information given,

r = 1.5

acceleration = 2cm^2/s

Recall, 100 cm = 1m

2 cm = 2/100 = 0.02m

Thus,

acceleration = 0.02m/s^2

Since the masses are identical, then m1 = m2

Each of them is accelerating at 0.02m/s^2

Recall,

Force = mass x acceleration

Force = m1 x 0.02 = 0.02m1 N

By substituting the given values into the formula, we have

0.02m1 = (6.673 x 10^-11 x m1 x m1)/1.5^2

m1 on the left cancels out one m1 on the right. It becomes

0.02 = (6.673 x 10^-11 x m1)/1.5^2

By crossmultiplying,

0.02 x 1.5^2 = 6.673 x 10^-11 x m1

0.045 = 6.673 x 10^-11 x m1

m1 = 0.045/6.673 x 10^-11

m1 = 6.74 x 10^8 kg

The mass of each ball is 6.74 x 10^8 kg

The blackbody radiation energy emitted by star a is 1/16 factor of star b energy.

We need to know about black body radiation to solve this problem. The energy radiated by a black body object is proportional to the area and the fourth power of temperature. It can be determined as

where P is power, A is surface area, e is emissivity, σ is Stefan Boltzmann's constant ( 5.67 x 10¯⁸ W/m²K⁴) and T is temperature.

From the question above, we know that

By using the black body radiation formula, the ratio of temperature is

Ta⁴ / Tb⁴ = Pa / Pb

Ta⁴ / Tb⁴ = Ea / Eb

We refer to any process where the velocity changes as acceleration. You can only accelerate by changing your speed, direction, or both as velocity is a function of both speed and direction. When two things are moved against one another, instant friction results. The motion will be opposed by the friction, who will also be working against it. When an item is in motion and its velocity changes, the concept of acceleration takes place. Friction, which opposes motion, always lowers acceleration. An object and a surface come into contact and cause friction. The features of the surface and the item as well as whether or not the object is moving determine its magnitude.

Explanation:

A tiger leaps horizontally from a 5.5 m rock with a speed of 3.6 m/s. So the tiger will land 2.772 m away from the base.

In mechanics, acceleration refers to how quickly an object's velocity alters in relation to time. The vectorized magnitude of accelerations. An object's acceleration is determined by the direction of the net force pushing against it.

Acceleration has a direction and a magnitude, making it a vector quantity. A vector quantity is a velocity as well. Acceleration is defined as the change in the vector of velocity over a period of time divided by the duration of the change.

According to the question, the given values are,

For y component :

Acceleration, a = -9.8 m/s²

Velocity, v₀= 0 m/s

Δy = -5.5 m

For x component :

a = 0 m/s²

v₀ = 3.6 m/s

Δy = v₀t + 1/2 at²

- 5.5 m = 0 + 1/2(-9.8)t²

t = 0.77 seconds

Δx = v₀t + 1/2 at²

Δx = (3.6)(0.77) + 0

Δx = 2.772 meters.
