The total distance you would have covered is equivalent to going around the earth 22 times.
Total distance traveledThe total distance traveled at a given speed and time of motion is calculated as follows;
Distance = speed x time
[tex]Distance = \frac{25 \ miles}{day} \times \frac{365 \ days}{1 \ year} \times 60 \ years\\\\Distance = 547, 500 \ miles[/tex]
Distance round the EarthThe distance round the earth or circumference of the earth of the earth has been given as 25,000 miles
Number of times round the earth[tex]n = \frac{547,500}{25,000} \\\\ n = 21.9 \ times \ \approx 22 \ times[/tex]

A person exerts 12.0 N on a 0.145 kg baseball for 0.480 s. What is the change in velocity of the base ball?
The change in velocity of the baseball is 39.72 m/s
What is change in velocity?
This is the difference between the final and the initial velocity of a body.
To calculate the change in velocity of the ball, we use the formula below.
Formula:Ft = mΔv.............. Equation 1Where:
F = Force exerted by the persont = timem = mass of the baseballΔv = Change in velocity.Make Δv the subject of the equation
Δv = Ft/m........... Equation 2From the question,
Given:
F = 12 Nt = 0.480 sm = 0.145 kgSubstitute these values into equation 2
Δv = (12×0.48)/0.145Δv = 39.72 m/s.Hence, The change in velocity of the baseball is 39.72 m/s

True or false: If the net external force on a system is zero, then the momentum of a system is constant even if objects in the system collide and exert forces on one another.
Answer:
True: if no external forces act on a system of objects then the total momentum of the system is unchanged.
It is true that if the net external force on a system is zero, then the momentum of a system is constant even if objects in the system collide and exert forces on one another.
What is momentum?Momentum is simply a quantity of motion. Quantity is measurable in this case because if an object is moving and has mass, it has momentum.
If an object does not move, it does not have momentum. However, it is important in everyday life, but many people are unaware of it.
According to the law of conservation of momentum, the momentum of a closed system is constant over time (conserved).
A closed (or isolated) system is one in which the mass remains constant and the net external force is equal to zero. Only when a system is closed does its total momentum become conserved.
Thus, the statement is true.

1. Every morning, from their house to the bus stop Raine has to walk 12 m west , 24 m North and 12m East in 80 s . a) What is the total distance travelled by Raine ? b) What is her average speed? c) What is the total displacement of Raine? d) What is her average velocity.
2. A bus travels on an interstate highway at an average speed of 85 km/h. How far does the bus travel in 1.5 hours?
3. A postman delivers a letter to a recipient who lives 24.0 km away from the post office. If it took the postman 0.50 h to reach the recipient's home, what is the speed of the postman?
Answer correctly pls i have no points left :(
Q1) [refer attached photo]
a) know that distance is the length between two points
so
the total distance travelled by Raine = 12m + 24m +12m
= 48m
b) Average speed is total distance travelled divided by total time taken by object.
= 48m / 80s
= 0.6 ms^-1
c) know that displacement is the shortest distance between two points.
total displacement = 24m
d) since we don't know about the velocities ( i.e initial and final ) average velocity can be found with displacement ( s ) divided by time interval ( t ) of the displacement.
avg. velocity = s/t
know that displacement is the shortest distance between two points.
displacement = 24m
average velocity = 24m/ 80s
= 0.3 ms^-1
Q2)
Average speed (85 km/h) is total distance travelled divided by total time taken (1.5 hours)
total distance = speed × time
= 85 × 1.5
= 127.5 km
Q3)
24km / 0.50h = 48km/h

Three materials were rubbed with an insulating cloth and tested to determine their charge. The table shows the results. Which material could be a metal?
Answer:
When two materials are rubbed together, the material with the greatest affinity for electrons is the material which takes electrons away from the other material. Saran wrap takes electrons from nylon and acquires the negative charge. In turn, the nylon loses electrons and becomes charged positively.

A child pulls a balloon for 12m with a force of 1.0N at an angle 60 degrees below horizontal.How much work does the child do on the balloon?
Answer:
Distance for which the balloon has been pulled by the child = 12 meter
Force applied by the child to pull the balloon = 1.0 Newton
The angle below horizontal = 60 degree
These information's are already given in the question. Based on the above information's the answer to the question can be easily determined.
We know that
Work done = Force * Distance * Cos(60)
= 1 * 12 * (1/2)
= 1 * 6
= 6 Joules
So the work done by the child is 6 joules. I hope the procedure is clear enough for you to understand. Based on the above mentioned procedure, you can always solve problems of similar kind without taking any outside help.

1. A virtual image is 3 meters behind a flat mirror and it is 2 meters tall. What is the height and distance from the mirror, for the object?
2. A concave mirror has a focal length of 1 meter. An object is 2 meters from the mirror. What is the image distance from the mirror?
3. Alens has a focal length of -10 cm. If the image of an object is located at -20 cm, what is the distance of the object?
Answer:
1. The distance of image from the plane mirror is same as the distance of object (person) from the plane mirror but the image is formed behind the mirror.
v=u=3 m
Thus distance between image and the person d=u+v=3+3=6 m
2.A concave mirror has a radius of curvature of 1.0 m. An object is placed 2.0 m in front of the mirror. Can you determine the location of the image (in cm)
1/v = 1/f - 1/u = 1/50 - 1/200 = 4/200 - 1/200 = 3/200
v = 200/3 c

Suppose wind blows on the model house from the left and
also produces an upward force on the roof. What reaction forces are
needed to support the weight of the roof and counteract forces from the wind?
The reaction force is the force that counterbalances the weight of the roof and acts upwards.
What is reaction force?The question is incomplete but I will try to help you the much I can. The image of the house is not shown hence the free body diagram can not be produced.
However, let me explain to you that force is a vector hence it has direction. The total resultant force is obtained by taking the direction of all the forces into account and this is called resolution of the forces. The reaction force is the force that counterbalances the weight of the roof and acts upwards.
