A motorcycle has a weight of 2000N. What is the mass of the motorcycle?
Answers
Answer:
One kilogram is equal 9.81 Newton’s. To convert Newton’s to kg you have to divide Newton’s by kg. In this scenario it would have to be 2000/9.81 which is 203.87 kg.

Scientists have concluded that Earth is at risk of future impacts with meteoroids. What are some criteria that engineers consider when they try to design technology to detect meteoroids and prevent collisions?
Science
Answers
Explain step by step
Explanation:
Collisions with asteroids, comets and other stuff from space have been responsible for huge landmarks in our planet’s history: global shifts in climate, the creation of our moon, the reshuffling of our deepest geology, and the extinction of species.
Asteroid threats pop up in the news every now and then, but the buzz tends to fizzle away as the projectiles pass us by. Other times, as with the 2013 Chelyabinsk meteor in Russia, we don’t know they’re here until they’re here.
Perhaps most useful to remember is that when near-Earth objects (including asteroids, comets and meteoroids) enter the atmosphere, they’re called meteors; and if there’s anything left when they hit the ground, the resulting object is called a meteorite. We tend to focus on asteroids when talking about potential collisions, because they’re more likely to hit us than other stuff like comets, but still big enough to pose a threat.
By using optical and radio telescopes, the meteoroids are characterized and their shape, rotation and physical composition are determined.
Scientists have considered some criteria to detect the meteoroids and prevent collisions so that earth is protected from their impact. This includes finding the position and size of the meteoroids and so the orbit of the earth could be changed and thus there is possibility for preventing collision.
By using optical and radio telescopes, the meteoroids are characterized and their shape, rotation and physical composition are determined. With the early recognition of the meteoroid movement and their position, the evacuation of people from the particular areas of possible impact can be done.

A bullet of mass 20g is horizontally fired with a velocity of 150m/s from a pistol of mass 2 kg. What is the
recoil velocity of the pistol?
Answers
Answer:
m1 = 20g (= 0.02 kg)
Mass of pistol, m2 = 2 kg
Initial velocity of the bullet (u1) and pistol (u2) = 0
Final velocity of the bullet, v1 = +150m s-1
Let v be the recoil velocity of the pistol.
Total momentum of the pistol and bullet after it is fired is
= (0.02 kg x 150 m s-1) + (2 kg x v m s-1)
= (3 + 2v) kg m s-1
Total momentum after the fire = Total momentum before the fire
3 + 2v = 0
→v = -1.5 m/s

You work for the police. An accident has happened. A farmer was taking his dairy cows for milking across a road. The crossing point was 100m from a blind bend. In normal conditions with an alert driver obeying the speed limit of 30m/s a car can safely stop before reaching the crossing point. Mr Hoyland was driving home, saw the cows around the bend and was unable to stop. He ran into one of the cows and killed it.
Answers
Answer:
Since the stopping distance is less than the thinking distance, Mr Hoyland is therefore responsible for the accident
Explanation:
. In normal road conditions and with an alert and sober driver the car
could have stopped before the crash.
2. The reaction time of an alert and sober driver is 0.6s.
3. The reaction time of a drunk driver could be 2s.
4. The initial speed of the car was 30m/s
5. From the time of applying the brakes the total braking distance in
normal conditions is 70m
6. From the time of applying the brakes the total braking distance in bad
conditions is 90m
7. From the time of applying the brakes in normal conditions the car would
reach 15m/s in 52m
You are a forensic expert working for the police. You must analyse the facts and produce a
report stating whether or not Mr Hoyland was responsible for the accident.
1. Calculate the thinking distance for a car travelling at 30m/s
2. Calculate the braking distance for a car travelling in normal conditions at 30m/s
3. Calculate the total stopping distance.
4. REMEMBER TO SHOW YOUR WORKING OUT
Challenge:
1. Is Mr Hoyland responsible for the accident?
2. Explain your answer giving CLEAR reasons for your answer and likely causes.
The Thinking distance = 100m
The breaking distance = 70m
A breaking distance = Stopping distance = 70m
Since the stopping distance is less than the thinking distance, Mr Hoyland is therefore responsible for the accident
A farmers accident.
As your work is for police an accident has happened. The farmer was taking his cows for milking across the road. The responsibility of both the farmers and driver in accident is taken into consideration.
The answers is before the crash.

A. Decreasing the surface area of contact
B. Increasing the surface area of contact
C. Putting a second brick on it
D. Decreasing the mass of the brick
10-H
IS
Answers
Answer:
B
Explanation:
Because it has to increase
force of friction = mu (coefficient of friction) * normal force
normal force = mass * force of gravity
In order to increase the frictional force, mass must be added to increase the normal force and thus the amount of applied friction.

Writing an Argument About Galetown’s Severe Storms Note: If you do not have access to Amplify Science at home, your teacher will provide you with an alternate way to complete this homework. In your final report to the citizens of Galetown, you will discuss the three claims and explain how all three factors can contribute to severe storms. Then, you will predict if the storms will always be severe. What caused Galetown to have more severe rainstorms this summer than in previous years?
Claim 1: The lake that was built near Galetown caused it to have more severe rainstorms.
Claim 2: Warmer weather caused Galetown to have more severe rainstorms.
Claim 3: Stronger winds caused Galetown to have more severe rainstorms.
Be sure to use some of the vocabulary words you have learned in both of your writing assignments: Word Bank air parcel, cloud,condensation, energy, evaporation, temperature, transfer, troposphere, water vapor, weather, wind
Recall from the previous activity which claims you think are best supported by evidence. Use these claims to explain what is happening in Galetown. You can use the data table and the words listed in the word bank above to help you with your report that answers the question: What caused Galetown to have more severe rainstorms this summer than in previous years? Press NEXT to move on to the second part of the written report. Write a 3-5 paragraph argumented essay
Answers
The claim that can be deduced is that B. Warmer weather caused Galetown to have more severe rainstorms.
What is a claim?It should be noted that a claim simply means the stance of an author in a literary work.
In this case, the claim is that warmer weather caused Galetown to have more severe rainstorms.
When the temperature of an air parcel begins higher, this will make it rise higher in the troposphere before the temperature of the air parcel and surrounding air are equal.

Do you think the number of asteroid samples a pod is carrying could make a difference? Might that explain why the same strength thruster force caused this pod to have a different change in velocity? Explain your ideas, even if you are unsure.
Please help!
Answers
Answer:
im not sure but from few stuffs i read online i will try and answer
Explanation:
The pod may be heavier or lighter than normal, depending on the number of
asteroid samples.
• Based on everyday experience, heavier objects are more difficult to move as
compared to lighter objects, which are easier to move
This pod moved differently because it was more massive. The kids in other missions were less massive, so the thursters stopped the pod. The thrusters were supposed to do stop the pod, but since it was more massive it only slowed. The force exerted by the thrusters wasn't great enough to stop the pod.
