releases thermal energy?
Explanation:
Respiration releases energy - it is an exothermic process. This means it releases heat energy.
The process which releases thermal energy is respiration.
What is thermal energy?The energy which increase the temperature is called the thermal energy.
Biomass energy is created but can not be stored. Same way, the respiration process which releases heat in form of air from nose or mouth. This process is exothermic.

A car travels 40 kilometers at an average speed of 80km/h and then travels 40 kilometers at an average speed of 40km/h. The average speed of the car for this 80-km trip is
Speed = distance / time
Part 1: 40 km at 80 km per goir = 0.50 hours
Part 2: 40 km at 40 km per hour = 1 hour
The time of the trip was 1.5 hours
Total distance was 40 + 40 = 80 ins.
Speed = distance / time = 80/1.5 = 53.33 km/he ( round answer as needed)
What is the speed of a vehicle with a distance of 88 miles and a time of 4 hours????
The answer you are looking for is 22 mph.
Solution:
s=speed
d=distance
t=time
Setting up the formula for the speed of an object with distance and time:
s=d/t
Substituting the given values,
s=88 miles/4 hours
So, therefore, the final answer is 22 mph.
I hope this helped answer your question for you. Good day to you.

It is more difficult to climb a vertical slope than a slanted slope because
Answer:
because in vertical slope force of gravity is more than compared to slanted slope
Answer:
because gravity is always pulling objects down so when you climb upward gravity weighs you down, you have to use effort to move yourself in the opposite direction that gravity is pulling you that is why it is harder to climb up a slope.

When an object of mass 200g is submerged in methanol, its apparent weight is 1.052N. When submerged in benzene its apparent weight is 0.951N. If the density of methanol is 0.8g/cm^3, What is the density of benzene?
When the object is submerged in methanol, it displaces an amount of methanol with weight 1.052 N, i.e. with mass = (1.052 N)/g ≈ 107.347 g. With a density of 0.8 g/cm³, this means the displaced methanol and hence the object itself have a volume of
v ≈ (107.347 g) / (0.8 g/cm³) ≈ 134.184 cm³
Likewise, when submerged in benzene, the object displaces 0.951 N of benzene, whose mass is (0.951 N)/g ≈ 97.041 g with the same volume as the object. So the density d of benzene is
d ≈ (97.041 g) / (134.184 cm³) ≈ 0.723 g/cm³

What is Newton's second law of motion ?
Newton's second law of motion states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it.
Initial mass = 950 kg
mass of piolet = 65 kg
reduced mass = 950 - 65 = 885 kg
according to Newton's second law of motion
force = mass * acceleration
3000 N = 885 kg * acceleration
acceleration = 3000 / 885 = 3.39 m/s^2 = 3.4 m/s^2
correct answer is D. 3.4 m/s2

How do Newton’s laws of motion explain why it is important to keep the ice smooth on a hockey rink so that players can pass a puck as quickly as possible?
Answer:
Newton's first law
Explanation:
Newton's first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force. Therefore, when the ice is smooth, friction gets lesser, and the force acted on that Puck will be decreased.
Answer:
The first law states that “objects at rest and objects in motion remain in motion in a straight line unless acted upon by an unbalanced force”. Keeping the ice smooth will make sure there is not friction, friction would slow the puck down

The first law states that “objects at rest and objects in motion remain in motion in a straight line unless acted upon by an unbalanced force”. Keeping the ice smooth will make sure there is not friction, friction would slow the puck down
