Answer:
4.266 m.
Explanation:
Given,
Speed of the electron = 7.50 x 10⁶ m/s
Magnetic field, B = 1 x 10⁻⁵ T
radius of circular path = ?
Using formula of radius of curvature of the charge particle
m is mass of electron
q is charge of electron
r = 4.266 m
Hence, radius of circular path is equal to 4.266 m.
Gravity on the surface of sun is given as
here we know that
now we will have
now we need to find the ratio of weight on surface of sun and on surface of Earth
so weight will increase by 28 times
Answer:
Explanation:
We shall find first the velocity of ball at the time when string breaks. Let it be v . During its fall on the ground , 1.02 m below, we use the formula
h = 1/2 gt² where t is time of fall .
1.02 = 1/2 x 9.8 x t²
t²= .2081
t = .456
During this time it travels horizontally at distance of 2.5 m with uniform velocity of v
v x .456 = 2.5
v = 5.48 m /s
centripetal acceleration
= v² / r where r is radius of the circular path
= 5.48² / .478
= 62.82 m /s²
1. I think a drum would be the easiest instrument to explain. You can vary the pitch and loudness by hitting it with different intensities or at different points or angles.
PS. I'm not talking about a drumset. I'm talking about an ordinary drum.
2. Different types of instruments sound different even though they play the same notes because they use different mechanisms for producing sound.
