Should be -9.8m/s^2!!! The force of gravity is the only thing pushing it down!!
Hope I helped you out!!
Answer: F =3.218 * 10^-11 N
Explanation: The relationship between electric field intensity and force is given by
F = Eq.
F= Force on electron
E = strength of electric field = 2*10^5
q= magnitude of proton charge = 1.609 * 10^-19c
F = 2* 10^5 * 1 609 * 10^-16
F = 3.218 * 10^-11 N
The answer would be C. (:
Answer:
4.0 Kg
Explanation:
From the question given above, the following data were obtained:
Velocity (v) = 48 m/s
Kinetic energy (KE) = 4632 J
Mass (m) =?
Kinetic energy can be defined as the energy possess by a moving object. Mathematically, it is expressed as:
KE = ½mv²
Where
KE => kinetic energy
m => mass of object
v => velocity
With the above formula, we can obtain the mass of the object as follow:
Velocity (v) = 48 m/s
Kinetic energy (KE) = 4632 J
Mass (m) =?
KE = ½mv²
4632 = ½ × m × 48²
4632 = ½ × m × 2304
4632 = m × 1152
Divide both side by 1152
m = 4632 / 1152
m = 4.0 Kg
Therefore, the mass of the object is 4.0 Kg
A circle is just a very very very special kind of ellipse.
So the correct choice is ' A ' .
