2800 m
Further explanationGiven
time = 80 s
average velocity = 35 m/s
Required
total distance before it broke down
Solution
Average velocity : total displacement : total time
Can be formulated
avg velocity = Δx : Δt
Input the value :
Δx=avg velocity x Δt
Δx = 35 m/s x 80 s
Δx = 2800 m
In addition, if we are asking for velocity, we must know the starting and ending points (displacement)
But if we calculate the total distance, what is written is the average speed
avg speed = total distance : total time

A group of friends are going bowling. They discuss how ball weight and speed can change the amount of
kinetic energy transferred to the pins.
They can use a 6 pound, 10 pound or 12 pound ball.
They can roll the ball at 10 miles per hour (beginner), 14 miles per hour (intermediate) or 18 miles per hour (professional) speed.
A. Describe a strategy that they could use to transfer the greatest amount of kinetic energy to the pins.
B. Explain the relationship between kinetic energy and strategy that you chose in part A.
C. Draw a model that demonstrates the energy transfers that occurred in the system.
Answers
Answer:
A. you would want to use the 12 ound ball and the 18 mph speed in order to transfer the most kinetic energy
B. KE= 1/2 MV^2 so you would want to maximize both your Mass(weight of the ball) and Velocity(speed of the roll) in order to achive the greatest KE.

Explain What the core muscles do and why it's important to have a strong set of core muscles.
Answers
Answer: Core muscles protect the spine and keeps it stabilized. Also they can help control movements such as walking and standing. The core helps transfer energy and help us move in different directions. It's important to have a strong set of core muscles.
Explanation:
Answer:
The core muscles stabilize and protect the spine. They help control all movements and make it possible for us humans to walk and stand up right. The core helps us transfer energy, shift our body weight and reach/move in different directions. It is important to have a strong set of core muscles because it makes everyday activities easier.

Please select the best answer from the choices provided
A
B
C
D
Answers
Answer:
Your answer should be B. a parabola.
Explanation:
The path of the projectile in the absence of friction is a parabola. Therefore, option (b) is correct.
What is the projectile motion?Projectile motion can be described as a form of motion experienced by a projectile that is projected near the surface of the earth and moves along a curved path under the action of gravity. This curved path is to be a parabola, but may also be a straight line in special cases when the projectile is thrown directly upwards.
The study of such motions is known as ballistics and the only force that is actively exerted is gravity, which acts downward, thus giving the object a downward acceleration toward the Earth’s center of mass.
No external force is required to maintain the horizontal velocity component of the object's motion because of the object's inertia. Other forces, such as aerodynamic drag or internal propulsion need additional analysis.
Therefore, the path of an object or projectile is generally parabola in the absence of friction.

what is the approximate increase in thermal energy in joules when the temperature of 15 grams of water is raised from 20° to 35° C. the specific heat of water is 4.19 j/g degrees Celsius
Answers
Answer:
942.75J
Explanation:
Change in thermal energy is equal to the mass of the given substance times the specific heat capacity times the temperature change.
We've already been given the specific heat capacity, the mass as well as the initial and final temperatures.
So change in temperature will be 35° - 20° = 15°
Thermal energy change = 15 × 15 × 4.19
The final answer is 942.75J
Hope that helped.

4. A force of 6.0 Newtons is applied to a block at rest on a horizontal frictionless surface over a 7.0 meter span. How much energy is gained by the block?
Answers
Answer:
42 Joules
Explanation:
Given that a force of 6.0 Newtons is applied to a block at rest on a horizontal frictionless surface over a 7.0 meter span. How much energy is gained by the block?
The parameters given are:
Distance covered = 7.0 m
The force = 6.0 m
The formula for work done is the product of force and distance. That is,
Work done = force × distance
Where work done is the same as energy.
Energy = force × distance
Energy = 6 × 7
Energy = 42 Joules.
Therefore, the energy gained by the block is 42 Joules.

Geologists use tools other than the law of superposition to help them with relative dating. Which statements describe those tools? Check all that apply.
Answers
Answer: Cross-cutting features are always younger than the surrounding rock.
When material erodes before sediment is deposited on it, a geologic gap results.
Explanation:
The options include:
1. An unconformity is created when lava pours out on Earth’s surface.
2. Faults are the result of volcanic activity.
3. Intrusions and extrusions are sedimentary formations.
4. Cross-cutting features are always younger than the surrounding rock.
5. When material erodes before sediment is deposited on it, a geologic gap results.
The law of superposition simply states that when there is a layers of rocks, we would see that the younger layers will lie and be on top of the layers that are older.
Other tools that can help scientist with relative dating are:
• Cross-cutting features are always younger than the surrounding rock.
• When material erodes before sediment is deposited on it, a geologic gap results.

HELP PLEASE
Answers
Theta is the angle between the force and the distance. Since they are going in the same direction, the angle is 0. Cos 0 is 1, so we can ignore that part.
The rest of the equation is force times distance.
540 * 11 = 5940 J.
