Answer:
6 kg
Explanation:
F=ma
F is Force(newtons)
m is mass(kg)
a is acceleration(m/s^2)
Plug in the numbers
3000 = m(500)
divide both sides by 500 to cancel out the 500.
3000/500=6
6 = m
6kg is the mass
Since Fg=(Gm1m2)/r^2, if the masses are halted the gravitational force will be effected as well. In this case, the gravitational force would be lessened as well.
Answer:
Since the waves must carry a great deal of visual as well as audio information, each channel requires a larger range of frequencies than simple radio transmission. TV channels utilize frequencies in the range of 54 to 88 MHz and 174 to 222 MHz. (The entire FM radio band lies between channels 88 MHz and 174 MHz.)
The speed of the particle when it enters the magnetic-field region is 120,000 m/s.
<h3>
Speed of the particle</h3>
Magnetic force on the particle is given as;
F = qvB
where;
- q is magnitude of the charge
- v is speed of the particle
- B is magnetic field strength
From Newton's second law, force on an object is given as;
F = ma
where;
- m is mass of the particle
- a is acceleration
ma = qvB
v = ma/qB
v = (3 x 10⁻² x 12)/(3 x 10⁻⁶ x 1)
v = 120,000 m/s
Thus, the speed of the particle when it enters the magnetic-field region is 120,000 m/s.
