Answer:
<h2>
The force is </h2>
Explanation:
According to newtons law on gravitation formula, which we are going to apply,
Where G represents universal gravitation constant,
Given data
m1= 90 kg
m2= 60 kg
d= 1 m
Substituting our given data into the formula we have
Wavelength should be in meters which is 0.023 m
c = 3.7 * 0.023 = 0.0851 (3 sf)
B. Transverse Wave this is the correct answer
(1) Speed is the ratio of the total distance covered by the object and the total time it takes for him to finish it.
Speed = distance / time
In this item, we are given that the distance is 20 kilometers and that the time it takes for the trip is 2 hours. Substituting the known values,
Speed = 20 kilometers / 2 hours
speed = 20 km/h
(2) Velocity on the other hand takes into account the displacement of the object from his original position. It is assumed that Jeremie was basically back to his original position after two hours. Hence, the velocity is equal to zero.
Answer:
(A) E = 0.84 N/C
(B) r = 4.74 meters
Explanation:
Given that,
Charge,
(a) The magnitude of electric field at a point 7.3 meters from this charge is given by :
E = 0.84 N/C
We know that electric field due to negative charge is inwards. So, the direction of electric field is towards the charge.
(b) Let at a distance of d meters the electric field have a magnitude of 2 N/C. It is given by :
r = 4.74 meters
Hence, this is the required solution.
