Answer:

The thermodynamic processes that occur in nature convert thermal energy into mechanical energy.

The thermodynamic processes that occur in nature are according to the law of thermodynamics.

The thermodynamics processes seen in nature are guided by the law of thermodynamics. The role of energy and heat transmission in physical systems is guided by these laws.

The laws are:

(1) Energy cannot be created nor destroyed in a system, according to the first law of thermodynamics, Also, referred to as the law of energy conservation. Only from one form to another, the energy can be transmitted or altered. Energy is conserved through natural processes, keeping the overall amount constant.

(2) Second law of thermodynamics: states that the overall entropy of an isolated system tends to increase over time in any natural process. This suggests that processes progress towards a state of increasing disorder.

Hence, the thermodynamic processes are guided by the law of thermodynamics.

Answer:

It is defined as an astronomical phenomenon which occurs when one spatial object comes within the shadow of another spatial object.

Given our understanding of physics, we can conclude that once the balloon is pushed under the surface, it will sink.

One key factor to take into account here is to remember that the density of a ballon can change when exposed to a higher pressure. This is due to the elastic nature of the material that makes up the ballon, and the nature of gas atoms that allow them to be compressed.

Therefore, when the balloon is pushed underwater, the surrounding water will squeeze the balloon, thus incrementing its density. Once the density of the balloon rises, this, in addition to the weight to which it is attached, will make it heavier than the water it is in, and the balloon will sink.

Hi there!

Since the ball is thrown with an initial HORIZONTAL velocity, we can treat this as a free-fall situation since the horizontal motion does NOT impact the ball's vertical motion.

We can use the derived kinematic equation:

[tex]t = \sqrt{\frac{2h}{g}}[/tex]

Plug in the given values:

[tex]t = \sqrt{\frac{2(150)}{9.8}} = \large\boxed{5.53 s}}[/tex]

The angle of projection is 0° because there is no vertical component to the velocity as the initial velocity is purely horizontal.

Range:

We can use the equation:

dₓ = vₓt

displacement (x direction) = velocity (x direction) · time

Used the solved-for time and given velocity:

dₓ = 100 · 5.53 = 553 m

Hi there!

When the acceleration of a block in SHM is 0 m/s², the NET FORCE must equal 0 N.

0 m/s² acceleration is obtained when the spring is at its equilibrium point, meaning that:

∑F = -kx (x = displacement from equilibrium point in meters)

If the block is at the equilibrium point, displacement = 0m, so:

∑F = -k(0) = 0 N

With Newton's Second Law, ∑F = ma. If the net force is 0 N, then there is no acceleration experienced by the block.

Thus, the other quantity that must be 0 is the block's NET FORCE.

b. Proton 2000 +1

c. Neutron 2000 0

2. a. An uncharged nucleon is neutron. It is a chargeless subatomic particle.

b. The particle with the least mass is electron. The mass of an electron is so small that it is considered to be negligible while calculating the atomic mass of an element.

c. The particle with the same mass as a neutron is proton. However if we see the absolute mass of neutron and proton then it is seen that neutron has a greater mass than proton.

d. The particle with the same amount of charge as an electron is proton. Note that the amount of charge is only same. Electron is negatively charged while proton is positively charged.

e. A particle that is negatively charge is electron. The relative charge of electron is -1.

Answer:

Rs 16.5 lakh is a charge of an electric car at a public charging station

Answer:

it is 1 / square root of the change in distance

Explanation:

since the equation of the gravitational force is

[tex]F=G{\frac{m_1m_2}{r^2}}[/tex]

then F and r are inversely related, by the equation

[tex]F \alpha \frac{1}{r^2}[/tex]

this means when F is multiplied by 2 then r^2 is multiplied by half

so when r is multiples by half we first square the number (0.5) ^ 2 = 0.25

so

[tex]F \alpha \frac{1}{(0.25)r^2}[/tex]

which means F is multiples by 1/0.25 or 4 when the radius is halfed

Answer:Work is a measurement of energy.

Power is a measurement of energy per time.

So, power measures how fast work is done.

If we raise 1kg up to a height of 1 meter it takes a certain amount of work. It doesn't matter if it takes us 1 second or 1 hour to raise it. It takes more power, energy per second, to raise it in 1 second than to raise it in one hour.

An engines power rating is in horsepower. A higher horsepower car engine will get a certain car up a hill more quickly than if it had a lower horsepower engine. Even though both engines did the same amount of work in getting the car up the hill

Explanation:

Ignoring air resistance

1) from vertical rest

s = ½at²

t = √(2s/a)

t = √(2(80)/9.8)

t = 4.040610...

t = 4.0 s

2) d = vt

   d = 25(4.0)

   d = 100 m

   v² = 25² + 2(9.8)(80)

   v² = 2193

   v = 46.8294...
