Answer:
The period of a wave is the time for a particle on a medium to make one complete vibrational cycle. Period, being a time, is measured in units of time such as seconds, hours, days or years. The period of orbit for the Earth around the Sun is approximately 365 days; it takes 365 days for the Earth to complete a cycle.
The gravitational force of the planet pulling on the sun is equal to the gravitational force of the sun pulling on the planet
Explanation:
We can solve this problem by applying Newton's third law, which states that:
<em>"When an object A exerts a force (called </em><em>action</em><em>) on an object B, then object B exerts an equal and opposite force (called </em><em>reaction</em><em>) on object A"</em>
In this problem, we can identify:
- The sun as object A
- The planet as object B
By applying Newton's third law, we can state that:
- The action is the gravitational force exerted by the sun on the planet
- The reaction is the gravitational force exerted by the planet on the sun
According to the law, the two forces are equal in magnitude and opposite in direction: so, we can conclude that
The gravitational force of the planet pulling on the sun is equal to the gravitational force of the sun pulling on the planet

Higher wattage means that the bulb will draw more current to it.
100W is more than 75W, so the answer is 2) 100W.
Hello
This question is to be tackled using vectors. When we look at the Southwest direction, we know it lies exactly between the South and West directions, producing an angle of 45 degrees. When we take sin(45) and multiply it by the original force, we obtain the component towards West; that is:
60 * sin (45) = 42.4 Newtons
And cos(45) gives us the force towards the South direction; that is:
60 * cos(45) = 42.4 Newtons
This can also be checked by using the formula of the magnitude of a vector and squaring 42.4, adding it to the square of 42.4 and then taking the square root of the answer.
sqrt(42.4^2 + 42.4^2) = sqrt(3600) = 60
ANSWER
C. 5 seconds to 7 seconds
EXPLANATION
This is a velocity time graph.
We can read the final velocity, v,the initial velocity u and the time easily from the graph.
See attachment for the initial and final velocities on each time interval.
So we can use either of the following equations to calculate the distance traveled.
Or
.
During the time interval 0 to 3, the distance traveled is,
.
During the time interval 3 to 5 seconds, the distance traveled is,
.
During time interval, 5 to 7 seconds the distance traveled is,
.
During time interval 7 to 8 seconds the distance traveled is
.
During time interval 8 to 10 seconds the distance traveled is
.
The correct answer is C.
