Answer:

В. An object with mechanical energy is always able to perform work.

Explanation:

Energy can be defined as the ability (capacity) to do work. The two (2) main types of energy are;

a. Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.

b. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.

Furthermore, the mechanical energy of a physical object or body is the sum of the potential energy and kinetic energy possessed by the object or body and it is measured in Joules.

Mathematically, it is given by the formula;

Mechanical energy = G.P.E + K.E

Hence, the true statement is that an object with mechanical energy is always able to perform work.

Answer:

[tex]\boxed {\boxed {\sf 8 \ m/s}}[/tex]

Explanation:

Speed is equal to distance over time.

[tex]s=\frac{d}{t}[/tex]

The distance is 400 meters and the time is 50 seconds.

[tex]d= 400 \ m \\t= 50 \ s[/tex]

Substitute the values into the formula.

[tex]s=\frac { 400 \ m }{ 50 \ s}[/tex]

Divide.

[tex]s= 8 \ m/s[/tex]

The speed of the car is 8 meters per second.

Answer:

Convection is what keeps the hurricane going in till the storm hits land.

Explanation:

Convection is the warm, moist current that rises above sea level and as it cools into water vapor it releases energy which a hurricane runs on. Once the hurricane hits land it continues to lose energy to keep it going because there's no convection from the sea currents rising above sea level to release energy.

All the vaulter's kinetic energy is transformed into gravitational potential energy. 7.35m is the that person's height.

Kinetic energy is the energy that an object has as a result of its movement. If we want to accelerate an object, we must apply force to it. Using force requires us to put in effort. After work is completed, energy is transferred to the object, and the object moves at a new constant speed.

The two most important factors influencing kinetic energy are mass and speed. Because an object's motion is determined by its velocity as well as its mass, though velocity is th

Given:

v = 12m/s

g = 9.8 m/s²

Kinetic energy = potential energy

K.E = P.E

1/2 mv² = mgH

H = v² /2g

H = 7.35m

Thus, 7.35m is the that person's height.

Gravity is a non-contact force that was observed famously by Sir Isaac Newton, who watched an apple falling from a tree to the ground. ... Newton was the first to realise that gravity existed in space and it was the force which holds the Moon in orbit around the Earth and planets in orbit around the Sun.

Answer:

The most important number's formal name is "equilibrium climate sensitivity," and it's meant to represent the new equilibrium in surface temperatures after a change in the amount of the Sun's energy trapped here on Earth rather than radiated back to space.

Explanation:

please give me brain list and follow

The average global temperature is the most important value when talking about climate change because the Earth's temperature is increasing day by day due to the trapping of the Sun's light energy.

The temperature is the degree of hotness or coldness of the object.

The equilibrium climate sensitivity is the equilibrium in Earth's surface temperature. After the Sun's trapped energy is reduced, the climate changes accordingly.

Thus, the average global temperature is the most important value when talking about climate change because the Earth's temperature is increasing day by day due to the trapping of the Sun's light energy.

Answer:

The Name of the heat energy from the is called solar energy.

Answer:

0 Joules.

Explanation:

Given the following data;

Mass = 80kg

Height = 10m

Gravitational potential energy (GPE) is an energy possessed by an object or body due to its position above the earth.

Mathematically, gravitational potential energy is given by the formula;

[tex] G.P.E = mgh[/tex]

Where;

G.P.E represents potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

We know that acceleration due to gravity is equal to 9.8m/s²

But since we're determining the gravitational potential energy just before the driver jump, the height would be zero (0) meters.

Gravitational potential energy= mgh

Gravitational potential energy = 80*9.8*0

Gravitational potential energy = 0 Joules.

This ultimately implies that, if an object or body hasn't moved (jumped) from its reference point, its gravitational potential energy would be equal to zero.

Answer:

A warm current

Explanation:

Answer:

A warm current is moving away from the equator towards the poles. The water in a warm current is warmer than the surrounding water.

Answer:

1. True.

2. False.

3. True.

Explanation:

A. True: An object has acceleration if its velocity is changing. In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.

B. False: Force is measured in joules. Force is a product of the mass of an object and its rate of acceleration. Thus, force is actually measured in Newton.

C. Gravity is a force. Gravity is considered to be a universal force of attraction which acts between all objects that has both mass, energy and occupy space. Therefore, it acts in such a way as to bring objects together.

Answer:

Explanation:

Given;

initial velocity of the rock, u = 15.5 m/s

at maximum height the final velocity of the rock, v = 0

The height risen by the rock is calculated as follows;

v² = u² - 2gh

0 = u² - 2gh

2gh = u²

h = u² / 2g

h = (15.5²) / (2 x 9.8)

h = 12.26 m

The time spent in air by the rock is known as time of flight, which is calculated as follows;

v = u - gt

0 = u - gt

gt = u

t = u/g

where;

t is the time to reach maximum height

t = 15.5 / 9.8

t = 1.58 s

Time of flight (time spent in air) is calculated as;

T = 2t

T = 2 x 1.58 s

T = 3.16 s.

The mass of an object is a measure of the object's inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it. The pull of gravity on the earth gives an object a downward acceleration of about 9.8 m/s2.
