The force of 454.4 N is required to give a mass of 71 kg and an acceleration of 6.4 m/s².
What is force?Force can be explained as the influence that is capable of changing the state of the body of motion or rest. The S.I. unit of measurement of force is Newton and force is a vector parameter. Force exerted on a body can change the direction as well as the speed of the moving body.
The force exerted on a system can be calculated from the product of the mass (m) and acceleration. The mathematical expression of the 2nd law of motion for force can be represented as:
F = ma
Given, the mass of the acting on an object, m = 71 Kg
The acceleration acting on an object, a = 6.4 m/s²
The force acting on the given mass can be calculated as:
F = ma = 71 × 6.4
F = 454.4 N
Therefore, the force required on an object is equal to 454.4 N.

Your friend wants to lose weight around the belly. Your friend is planning to do crunches every day to lose the weight, but is not planning on doing any other exercises. Do you think this strategy will be effective? Why or why not? What can your friend do to increase the pace of weight loss? Explain your answer. Please hurry I need a paragraph!!!
But I will put it in my own words so it won't be plagerism!
Answer:
i don't think it will work
Explanation:
because in order to lose weight, you have to do more than one stretch because weight loss takes multiple steps and not just one exercise, it would also involve you to eat healthy and to increase the pace, your friend could go running, do yoga, eat healthier, drink more water, and do more than just a core workout and etcetera.

7. The night of desest is very cold and the day is very
hot
Give reason
Answer:
1) Sand cannot hold the heat. It acts like a mirror to the sun. During the daytime, it stays warm, and when the Sun is absent it loses all its heat making the nights colder. There's nothing in the desert that can either absorb heat from the sun or hold it on the surface when the sun is set.
2) Deserts are hot primarily because of a lack of water. When the sun shines on the ground, all of the absorbed sunlight goes into raising the ground's temperature. DESERTS ARE COLD AT NIGHT:Because of the lack of water in the ground, and little water vapor in the air, most deserts can get quite cool at night.
3) The temperature in the desert can change drastically from day to night because the air is so dry that heat escapes rapidly at night. The daytime temperature averages 38°C while in some deserts it can get down to -4°C at night. The temperature also varies greatly depending on the location of the desert.
10 Why is it important for basketball players to wear shoes with tread when playing? to increase the speed of the player to decrease the force between the player and the floor to increase friction between the floor and the player's feet to decrease the amount of force needed for the player to move
Answer:
to increase friction between the floor and the player's feet
Explanation:
It is important for basketball players to wear shoes with tread when playing in order to increase friction between the floor and the player's feet.
Friction between the floor and the player's feet will ensure that players do not trip easily during the course of playing. It also helps in such a way that players can stop quickly and run in the opposite direction without losing traction. Without this friction, it would be virtually impossible to play the game.
