When distance<span> is increased the amount of </span>force<span> needed will depend on the </span>mass<span> of the object. </span>
Answer: 13%
Explanation: The reason this is 13 is because you can eat carlories and you can also be an amazing person 200 calories and 7 grams
The distance starting from the point to the lighthouse would be regarded as the hypotenuse.
And also will be the radius of the circle the beam of light is generating at that point.
So get the radius first
r = sqrt (1^2 + 5^2)
r = 5.099 km
find the circumference:
C = 2*pi * 5.099 km
C = 2 * 16.01898094
C = 32.04 km
Then find the speed in km/sec
One revolution: 60/2 = 30 sec per revolution
Speed = 32.04 km/30 sec
S = 1.068 km/sec is the speed of light
Answer:
Explanation:
Let r be the rate of the slower walker in mph
[r + (r + 1.7)](2) = 13
(2r + 1.7)(2) = 13
4r + 3.4 = 13
4r = 9.6
r = 2.4 mph
r + 1.7 = 4.1 mph
As per the third law of Newton, the force exerted by the boat over the student is equal in magnitude to the force that the student exerted on the boat.
So, calculate the force on the student using the second law of Newton, Force = mass * acceleration.
Force on the student = 60 kg * 2.0 m/s^2 = 120 N.
=> horizontal force exerted by the student on the boat = 120 N
Answer: option d. 120 N. toward the back of the boat.
Of course it is toward the back because that is where the student jumped from..
