Answer:
Astronomical location of Mount St. Helen's is 46°12′01″N 122°11′22″O, meaning that such statovolcano is located at middle latitudes. In middle latitudes, troposphere is 17 kilometers high, which is below stratosphere, whose height is 10 kilometers at middle latitudes. Hence, the eruption of Mount St. Helen's in 1980 contiminated troposphere and lower parts of stratosphere due to volcanic ash.

A 60 W bulb is supplied with 36 000 j of energy how long is the bulb on for
Answer:
Time = 600 seconds
Explanation:
Given the following data;
Power = 60W
Energy = 36000
To find the time;
Energy = power * time
Substituting into the equation, we have;
36000 = 60 * time
Time = 36000/60
Time = 600 seconds.
Therefore, the bulb was on for 600 seconds.

On top a coiled spring labeled Wave A with coils, which are widely spaced then tightly spaced then widely space. On bottom a coiled spring labeled Wave B with coils, which are widely spaced then very tightly spaced then widely space.
Which statement can be made about waves A and B?
Wave A has a lower amplitude than Wave B.
Wave A has a higher amplitude than Wave B.
Wave A has a lower frequency than Wave B.
Wave A has a higher frequency than Wave B.
Wave A has a lower frequency than Wave B.
Explanation:
Frequency is the number of waves passing through the unit time.
As the statement of the question says that the coils in wave A are widely and tightly spaced.
While in wave B the coils are widely and very tightly spaced which means the number of coils is more and the frequency of wave B is more than wave A.
Therefore more coils will pass through a fixed point in unite time and more will be the frequency.

A train is moving with a velocity of 70 km/h.
If north is taken as the positive direction, what is the direction of movement of the train?
It is moving north but is speeding up. ,
It is moving north. ,
It is moving south.
It is moving south but is speeding up.
Answer:
B: It is moving north.
Explanation:
We are told that a train is moving with a velocity of 70 km/h.
Now, we are also told that the positive direction is north.
This means that the train is moving in the northern direction.
We can't say if it is speeding up or not because we are not given the acceleration.
Thus, option B is correct
Answer:
It is moving north.
Explanation:
I took the test.

Distance divided by time is known as
Distance divided by time is known as the speed of the given body or the object the result we get out by dividing the distance from the time is a scalar quantity as it does not depend on the direction of the moving object.
What is speed?The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object. The unit of speed is a meter/second. The generally considered unit for speed is a meter per second.
Let us suppose an ant is moving and it covers a total distance of 2.5 meters in 25 seconds, then if we divide the time taken by the ant by the distance traveled by the ant we would get the speed of the ant.
Thus, distance divided by time is known as speed.

if a 580 N net force acts on a 40 kg what will the acceleration of the car be
Answer:
I think u have to do 580N times 40KG
Answer: DONT MULTIPLY, YOU DIVIDE THEM
Explanation:
F = mass x acceleration
580 N = (40 kg)(a)
580/40 = 14.5
a = 14.5 m/s²
A bullet with a mass of 0.3 kg is fired out of a gun with a mass of 4 kg at 600 m/s. What is the recoil velocity on the gun?
200 m/s
45 m/s
2400 m/s
90 m/s
Answer:
According to the Conservation of Momentum,
Momentum of the gun = momentum of the bullet
M(gun)×V(gun)=m(bullet)×v(bullet)
4kg × V = 0.3kg × 600m/s²
V = (0.3 × 600)/4 = 45 m/s
The recoil velocity on the gun is 45 m/s
45 m/s is the right answer.The third one pls help
Answer:
20 ms¯¹
Explanation:
3. Determination of the final velocity
From the question given above, the following data were obtained:
Time (t) = 4 s
Acceleration (a) = 5 ms¯²
Initial velocity (u) = 0 ms¯¹
Final velocity (v) =?
Acceleration is simply defined as the change in velocity per unit time.
Mathematically, it can be expressed as:
Acceleration (a) = final velocity – Initial velocity / time
a = v – u / t
With the above formula, we can obtain the final velocity of the car as follow:
Time (t) = 4 s
Acceleration (a) = 5 ms¯²
Initial velocity (u) = 0 ms¯¹
Final velocity (v) =?
a = v – u / t
5 = v – 0 / 4
5 = v / 4
Cross multiply
v = 5 × 4
v = 20 ms¯¹
Thus, the final velocity of the car is 20 ms¯¹
If an object moves at a constant speed, the line on a distance/time graph would be
Answer: straight
Explanation:
If an object moves at a constant speed, the line on a distance/time graph would be straight.
Since the object is moving at a speed which is constant, it'll have a straight line because the direction of the object is not changed.
In handball, once a player possesses the ball,
how many steps are they allowed to take?
How does this help with the speed of the
game?
Answer:
If possessing the ball, players must dribble (not similar to a basketball dribble), or can take up to three steps for up to three seconds at a time without dribbling. No attacking or defending players other than the defending goalkeeper are allowed to touch the floor of the goal area (within six metres of the goal).

If the force of a 10 kg car traveling in a circular path is 900n and the circle has a diameter of 20 m what is the velocity of the car
Answer:
the velocity of the car is 30 m/s.
Explanation:
Given;
Centripetal force on the car, F = 900 N
mass of the car, m = 10 kg
diameter of the circular path, d = 20 m
radius of the circular path, r = 10 m
The velocity of the car is calculated as follows;
[tex]F = \frac{mv^2}{r} \\\\mv^2 = Fr\\\\v^2 = \frac{Fr}{m} \\\\v = \sqrt{\frac{900 \times 10}{10} } \\\\v = 30 \ m/s[/tex]
Therefore, the velocity of the car is 30 m/s.

What is the acceleration of the cyclist from 175 to 200 seconds? A. -12 m/s2 B. 0m/s2 C. 12 m/s2 D. Can't be determined
Answer:
The correct answer is D
Explanation:
The expression for the accelerated ion is
a =[tex]\frac{v_f - v_o}{ \Delta t}[/tex]
therefore to find the variation of time is needed, which is a data given in the problem.
It also needs to be emptied of speed, which is not given.
Consequently we cannot find the acceleration in this exercise.
The correct answer is D

Please help- Determine the relationship between potential and kinetic energy in a system.
Answer:
See the explanation below.
Explanation:
At the highest point is where potential energy is maximum and kinetic energy is zero.
Because potential energy is defined as the product of mass by gravitational acceleration by height, this is expressed within the following equation:
[tex]E_{pot}=m*g*h[/tex]
where:
Epot = potential energy [J]
m = mass [kg]
g = gravity acceleration [m/s²]
h = elevation [m]
As we can see, if the body is located at the highest point with respect to the ground, potential energy has the maximum value. Meanwhile, the kinetic energy is zero because there is no movement.
At the lowest point is where the kinetic energy is maximum and the potential energy es zero.
When the body is in the lowest location, the height is zero, therefore potential energy is zero (h = 0). But the body is moving with a certain velocity that is we have kinetic energy.
