Answer:
Explanation:
As we know that during the projection of rocket the total mechanical energy is conserved as there is no friction in it's motion
So we will have
now divide whole equation by mass of the object
now we can rearrange above equation to find gravitational constant
So above is the expression for gravitational constant G
Answer:
200N
Explanation:
Given parameters:
Mass of wagon = 100kg
Acceleration = 2m/s²
Unknown:
Force on the wagon = ?
Solution:
From Newton's second law of motion:
Force = mass x acceleration
Now insert the parameters and solve;
Force = 100 x 2 = 200N
The individual charges flow from negative to positive in the circuit
(conventional) current flows clockwise (positive to negative)
Ip = Ib = In
Q (charge) = I*t (current*time)
less charge = less current
Answer:
7.85 m/s^2
Explanation:
linear or tangential acceleration= dv/dt
⇒
=0.83 m/s^2
radial acceleration is given by =
⇒
= 7.81 m/s^2
total acceleration
putting values we get
= 7.85 m/s^2
Answer:
Doppler radar is very useful for determining the presence of a tornado.
Explanation:
Doppler radar is the special type of radar that uses the principal of Doppler effect to find velocity about the object at any distance. It can be used for many purpose like radar gun, aviation, on air weather etc.
Thus, It can also determine the presence of tornado.
