A rock is thrown straight up with an initial speed of 15.5 m/s . It is caught at the same distance above the ground . How high does the ball rise? How long does the ball remain in the air?
Answer:
The height risen by the rock is 12.26 mThe time spent in air by the rock is 3.16 sExplanation:
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.

Decide whether these are true or false. Type out the whole sentence in the space and type a "T" beside the letter. Retype the sentences that are not correct. A. An object has acceleration if its velocity is changing. B. Force is measured in joules. C. Gravity is a force.
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.
Why is average global temperature the most important value when talking about climate change?
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.
What is temperature?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.

What has gravity led scientists to understand?
Answer:
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:
Newton's theory had prove that all objects, as small as an apple and as large as a planet, are subjected to gravity. Gravity helped to keep the planets rotating around the sun and creates the ebbs and flows of rivers and tides.Pls someone help me!!!!!

A zebra drinks from a watering hole and is ambushed by a crocodile. What's more important and why: the zebra having a high maximum speed or a high acceleration?
Answer:
before this type of attack, high acceleration is the most important thing.
Explanation:
As the zebra is ambushed by the crocodile the most important thing is a quick reaction, in this attack the most likely is that the crocodile is in the water so it cannot run after the zebra.
Consequently, before this type of attack, high acceleration is the most important thing.
An 80 kg diver jumps from a 10 m high platform. What is the gravitational potential energy of the diver right before they jump (top of platform)
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.

Explanation:
Assume that a vaulter is able to carry a vaulting pole while running as fast
as Carl Lewis in his world record 100-m dash (around 12 m/s). Also assume
that all of the vaulter's kinetic energy is transformed into gravitational
potential energy. What vaulting height could that person attain?
(Hint: Use the equation 5 mu? = mgh.)
Answer:
5mu = carry a vaulting pole ( 12 m/s) Also
fast
All the vaulter's kinetic energy is transformed into gravitational potential energy. 7.35m is the that person's height.
What is kinetic energy ?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.

what is the relationship between speed and kinetic energy? (In other words, how are the two related to one another?) Explain.
Answer:
The kinetic energy of an object is directly proportional to the square of its speed. That means that for a twofold increase in speed, the kinetic energy will increase by a factor of four.

Plssss help———what is the difference between the weight of an object and the mass of an object? (Needs to be 4-5 complete sentences)
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.

How does convection play a role in hurricanes
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.
