How much force is needed to accelerate a 1.5 kg physics book to an acceleration of 6
m/s^2?
Answer:
Force = 8.0 k g m / s
Explanation:
Force = mass x acceleration
Mass = 4.0 k g Acceleration = 2.0 m / s 2
Hence,force = ( 4.0 x 2.0 ) k g m / s 2 = 8.0 k g m / s 2
Write some harms of friction.
Answer:
Friction produces unnecessary heat leading to the wastage of energy. The force of friction acts in the opposite direction of motion, so friction slows down the motion of moving objects. Forest fires are caused due to the friction between tree branches. However, friction can also cause problems in a car. Friction between moving engine parts increases their temperature and causes the parts to wear down. Friction can be both harmful and helpful, so it may be necessary to decrease or increase friction.
Answer:
Friction had many disadvantages and these are the har,s of friction too.
Explanation:
Disadvantages of friction are mainly forest fires, decreasing life expectancy of vehicles, damages many machines, generates heat, wear and tear, wastage of force/energy, etc. When two things in a forest rub against each other through an amount of force, friction will be present and it will cause a spark. This spark will be continued into a fire because of other materials like wood in the forest causing a forest fire. Secondly, vehicles work through moving many internal machines in them; this again includes friction and friction can damage the machines so to prevent it ppl grease the machines. decreasing life of vehicles is just a larger view of damaging the machines as this disadvantage of friction can be used anywhere. Wastage of force/ energy because when we roll a ball on a surface we have to put force on the ball to make it move forward but because friction moves in the opposite direction energy/force will be wasted there. Generating heat and wear & tear are some factors of friction which is also a harm.

In what ways is thermal energy transferred during physical and chemical changes
Explanation:
chemical changes
>produce new substances w/ different chemical structure/ properties
> thermal energy can be used to BREAK bonds (endothermic)
>thermal energy can be transferred to a chem rxn to help form new products (endothermic)
> heat can be released by an exothermic chemical reaction (excess energy- the total energy used to break bonds is less than energy released in forming new bonds)
physical changes
>does not result in new substances (typically changes in state- solid, liquid, gas)
> thermal energy can be transferred to EVAPORATE water (add thermal E... water (liquid) to steam (gas)) or FREEZE water (remove thermal E... water (liquid) to ice (solid))
Which of the following periodic properties increases as you move from left to right across the periodic table?
A.
nuclear charge
B.
All of these answer choices are correct.
C.
electron affinity
D.
electronegativity
Answer:
the answer choice is B
Explanation:
as we move from left to right , the atomic size decreases due to higher number of protons in the nucleus, which are able to attract the electrons more strongly. and so the electronegativity and electron affinity increases for the same reason. the nuclear charge increase due to more protons , and without an increase in inner electrons , there is less shielding effect. so effective nuclear charge increases.
Answer: B. electronegativity
Explanation: Electronegativity generally increases as you move of the periodic table and as you move to the right. All the other answers listed decrease as you move up a column of the periodic table.

By comparing fossils of a species from long ago to those of today, we can conclude that *
1 point
fossils show no evidence of relationship between the past and present.
past species were more likely to be fossilized than today's.
today's species evolved from those of the past.
present species live longer.
Answer:
today's species evolved from those of the past.
Explanation:
By comparing fossils of a specie from long ago to those of today, we can conclude that today's species evolved from those of the past.
Fossils are the preserved remains of ancient life forms found within sedimentary bed layers. These fossils helps scientists to understand ancient life forms. According to the discovery of Charles Darwin, organisms have evolved and are still evolving. Understanding past life forms gives a way to characterize present day species better.Of all the Group 13 metals, I am the one with the least mass.

A person or object may have stored energy because of its
Answer:
A person or object may have stored energy because of its....
potential energy
A person or object may have stored energy because of its position and the energy is called potential energy.
What is potential energy?The relative positions of different system components determine the potential energy, which is stored energy. When a spring is compressed or stretched, its potential energy increases.
If a steel ball is raised above the ground as opposed to falling to the ground, it has more potential energy. It is capable of performing more work when raised.
Potential energy is a characteristic of systems rather than of particular bodies or particles; for instance, the system made up of Earth and the elevated ball has more potential energy as they become further apart.
In systems having components whose forces on one another rely on their configuration, or relative positions to one another, potential energy is generated.

What is the mass of a car traveling at 5.6 m/s with a momentum of 3723 kg*m/s?
Answer:
m = 664.821 kg
General Formulas and Concepts:
Physics
p = mv
p = momentumm = mass (kg)v = velocity (m/s)Explanation:
Step 1: Define variables
m = unknown
p = 3723 kg * m/s
v = 5.6 m/s
Step 2: Find mass
3723 kg * m/s = m(5.6 m/s)

How does the change in the state of matter occur? Write with example
Answer:
When matter changes from one state to another, it either absorbs energy—as when chocolate melts—or loses energy. For example, if you were to place the melted chocolate in a refrigerator, it would lose energy to the cold air inside the refrigerator. As a result, the liquid chocolate would change to a solid again.

A. Buoyancy
B. Atmospheric pressure
C. Gravity
D. Density
The force corresponds to the question mark in the given figure is known as Gravity. Hence, option (C) is correct.
The given problem is based on the concept of equilibrium of forces. The forces that causes the net motion of an object to be zero, is known as equilibrium of force.
In the given problem, the lift of an aircraft will be due to the Buoyant force due to the air as a medium. The drag acting the opposite direction of motion of aircraft, tends to resist the motion. The thrust force acting on the aircraft is due to the component of aircrafts, which causes the aircraft to move forward.And the question mark shown in problem is somehow pointing the gravitational force, which always acts in downward direction. And gravitational force highlights the gravity.Thus, we can conclude that the force corresponds to the question mark in the given figure is known as Gravity. Hence, option (C) is correct.

9) Zane has an elastic water balloon launcher that can fire balloons at an angle of [38.0o] from the surface of the ground. If the initial velocity is 25.0 m/s, find how far away are the balloons are from the launcher when they hit the level ground again.
Answer:
127.6 m
Explanation:
Given that Zane has an elastic water balloon launcher that can fire balloons at an angle of [38.0o] from the surface of the ground. If the initial velocity is 25.0 m/s,
The horizontal initial velocity will be:
U = 25cos38
U = 19.7 m/s
To find how far away are the balloons are from the launcher when they hit the level ground again, we will first calculate the total time spent before using the range formula
To calculate the total time, let's use the formula below:
T = 2U/g
T = (2 × 25)/9.8
T = 50/9.8
T = 5.1s
Range = UT
Since horizontal acceleration = 0
Range = 25 × 5.1
Range = 127.55 m
Therefore, the balloons are approximately 127.6m away from the launcher when they hit the level ground again
