Thermometer-temperature
Wind vane -wind direction
Anemometer- both wind speed (and direction)
Hygrometer- humidity
Answer:
3.8379 meters
Explanation:
A charged particle into an uniform magnetic field describes a circular movement with radius "r" acording to the equation r=(m*v)/(q*B), where m is the mass of the particle, v its velocity, q the charge, and B the perpendicularly uniform magnetic field. Replacing your value on this equation, the radius is 3.8379 m. I suggest to verify the value of the magnetic field, because 9.4 is a extremely high magentic field.
Answer:
M = 3.485 kg
m = 1.605 kg
Explanation:
F = 0.98 x 10^-8 N
r = 19.5 cm = 0.195 m
M + m = 5.09 kg ...... (1)
By use of Newton's gravitational law
F = G m1 m2 / r^2
0.98 x 10^-8 = 6.67 x 10^-11 x M x m / (0.195)^2
M x m = 5.59
M - m = 1.88 .........(2)
By solving the equation (1) and equation (20, we get
M = 3.485 kg
m = 1.605 kg
