Amy weighs 35 kg and her dad weighs 85 kg. They are roller skating. Amy challenges her dad to race. They stand poised at the starting line. Her dad yells, “Go!” Who will go faster and why?
Answer:
Amy because she was less than her dad and due to the dads weight being more it'll add friction to the skates which will slow him down.
Explanation:
Answer:
Amy will win because she ways less than her dad.

Explanation:
A force of 1000 pounds drags a truck 50 feet in 10 seconds.
How much work is accomplished?
How much power was required?
Work = 50, 000 ft-lbs, Power = 5000 ft-lbs/sec
Work = 50,000 ft-lbs, Power = 500 ft-lbs/sec
Work = 5,000 ft-lbs, Power = 500 ft-lbs/sec
Answer:
The first one (Work = 160,000 Nm, Power = 160, 000 Nm/sec)
Explanation:
hope this helps :)
A force of 1000 pounds drags a truck 50 feet in 10 seconds. then the work accomplished is 50000 lbs feet and the power required was 5000ft-lbs/sec.
What is Force ?Force is responsible for the motion of an object. it produces acceleration in the body. According to newton's second law force is mass times acceleration i.e. F =ma. Its SI unit is N which is equivalent to kg.m/s². There are two types of forces, balanced force and unbalanced force. Balanced forces are those forces which are opposite in direction and equal in magnitude. When Net force acting on a body is zero then we call it as balanced force. Balanced force is not responsible for the motion of the body. ex. when two persons pulling rope on both end with equal magnitude which cause them to be balanced force have 0 net force. Unbalanced forces are those when resultant of all the forces is not equal to zero is called as unbalanced force. unbalanced force is responsible for the motion of the body.
Given,
F = 1000 pound
s = 50 feet
t = 10 s
Work = F.s = 1000 * 50 = 50000 lbs feet
Power = Work/time = 50000/10 = 5000ft-lbs/sec
Hence option A is correct.

A student lists some possible ways to investigate the transfer of kinetic energy using ice in a sample of water. The procedure would be best to investigate the transfer of kinetic energy is Determine temperature and mass of water. Put ice in water. Record the time for ice to melt. Therefore, option 4 is correct.
What do you mean by kinetic energy ?The term kinetic energy is define as the energy of motion, observable as the movement of an object. The formula of kinetic energy is as follows:
Kinetic energy = 1/2 mv²
Kinetic energy exists in every moving object and particle. Kinetic energy is demonstrated by a person walking, a soaring baseball, a crumb falling from a table, and a charged particle in an electric field.
Kinetic energy is the energy held by a moving object. Kinetic energy exists in the earth's rotation around the sun, you walking down the street, and molecules moving in space.
Thus, option 4 is correct.

FIRST ONE TO ANSWER CORRECTLY GETS BRAINLIEST!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass.
Explanation:
Interesting fact...
Why are there differences between the cooling rates of sand and water? Sand cools off faster than water because sand is a solid. Water heats up slower and cools off slower than sand. Sand heats up faster and cools off faster than water.
As a variable and to count as land. As if you were at a beach, this sand would count as the sand that the sun would be beaming on. ^^
