What net force will make a 5kg bowling ball accelerate by 1.5m/s squared

Answers

Answer 1

Answer: F = ma
F = force
m = mass
a = acceleration

1.5 m/s^2 = a
5 kg = m
F = ?

F = 5 * 1.5
F = 7.5 Newtons

Answer would then be : Force = 7.5 N

Why is respiration an exothermic reaction? A. a large amount of energy is released into its surroundings B. the heat content, q, of the reaction is positive C. a large amount of energy is required to activate the reaction D. there is no exchange of energy between the system and the surrounding

Answers

A. a large amount of energy released into its surrounding

During the respiration, glucose molecules are converted to other molecules in a series of steps. They finally end up as as carbon-dioxide and water.

The overall reaction is

C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + 2805 kJ

The reaction is exothermic reaction because C=O and O-H bonds in the products are so much more stable than the bonds in the reactants.

Bond energy is the average needed to break a bond.

Some bond energies are:
C-C = 347 kJ/mol
C-H = 413kJ/mol;
C-O = 358 kJ/mol;
O-H = 467 kJ/mol;
O=O = 495 kJ/mol;
C=O = 799 kJ/mol

Final answer:

Respiration is an exothermic reaction because it releases more energy than it absorbs in the form of heat to its surroundings. All such reactions require an initial energy input, known as 'activation energy', to start the reaction. In an exothermic reaction, the heat content 'q' is negative, showing the transfer of thermal energy from the system to its surroundings.

Explanation:

Respiration is an "exothermic reaction", which means it is a chemical reaction that releases energy in the form of heat to its surroundings. This is achieved through the catabolism of foods in your energy bar, which is an example of an exergonic reaction. This reaction absorbs some of the chemical energy stored in the food, turns it into molecules your body can use, and releases the excess energy into the surroundings. However, all chemical reactions, including exothermic and endothermic reactions, require a small amount of energy to activate them.

During an exothermic reaction, there is a net release of energy despite this initial energy input. The energy given off is more than the energy absorbed. This process represents the concept of 'activation energy', an energy barrier that needs to be overcome for the reaction to proceed. Therefore, the heat content, often represented as 'q', is negative in an exothermic reaction, indicating that the system gives off thermal energy to the surroundings, making the surrounding environment warmer.

A person of mass 80 kg stands on Earth's surface. What is his weight?

Answers

Weight is always (mass) times (gravity in the place where you are).

On Earth, acceleration due to gravity is 9.8 m/s² ,
so the person's weight is

(80 kg) x (9.8 m/s²) = 784 newtons .

(about 176.4 pounds)

The answer is 784 newtons. I hope that helps you :]

A steel block has a volume of 0.08 m³ and a density of 7,840 kg/m³. What is the force of gravity actingon the block (the weight) in water?
A. 5,362.56 N
B. 7,600.18 N
C. 6,700.56 N
D. 6,150.64 N

Answers

The mass of the block is

   (0.08 m³) x (7,840 kg/m³) = 627.2 kg.

The force of gravity on the block is

   (mass) x (gravity)

   = (627.2 kg) x (9.8 m/s²)

   =    6,146.6 newtons .

As long as the block is on Earth, that's its weight. In vacuum, in air,
in water, in sugar, in bed, in trouble, or in molasses ... that's the force
of gravity attracting it toward the center of the Earth.

If it happens to be in water, then there's another force acting on it ...
the upward force of buoyancy, equal to the weight of the water it
displaced.

The block displaced 0.08 m³ of water, so the buoyant force is the weight
of 0.08 m³ of water.

The density of water is 1,000 kg/m³, so the mass of the displaced
water is

    (0.08 m³) x (1,000 kg/m³) = 80 kg .

and its weight is (80 kg) x (9.8 m/s²) = 784 newtons.

That's the buoyant force on the block . . . 784 newtons.
It acts upward on the block, opposite to the force of gravity.
So, if there's a bathroom scale on the bottom of the pool,
and the block is resting on it, the scale will read

   (actual weight) minus (buoyant force)

   = (6,146.6 newtons) - (784 newtons) = 5,362.6 newtons .

The real weight of the block is 6146.6 newtons.
That's choice-D.

The apparent weight of the block in water is 5,362.6 newtons.
That's choice-A.

The question asked for the force of gravity on the block, and then
in parentheses it says (weight). Both of these are 6146.6 newtons.

If you answer 'D', and your answer is marked wrong and somebody
tries to tell you that the correct answer is 'A', then I want you to either
show them what I have written here, or else tell them to come see me,
and I will straighten them out.

Friction causes kinetic energy to be converted into what energy

Answers

Friction causes kinetic energy to be converted into 'thermal energy'. The answer to this question is 'thermal energy'. An example would be if something is being rubbed against another object, there is friction and thermal energy will be produced. I hope this helps you on your assignment! You're welcome.

Final answer:

Friction causes kinetic energy to be converted into thermal energy.

Explanation:

Friction causes kinetic energy to be converted into thermal energy, among other forms of energy. When an object is in motion and experiences friction, the work done by friction is negative, which reduces the object's kinetic energy. This converted energy is often released as heat.
