Mass=highest of neutron almost same of proton and mass of electrons is 1/1840 of protons the charge on neutron is neutral positive on Proton and negative on electrons Neutron and protons are inside the nucleus and keep the electron orbiting around them in different shells..
Answer:
6.75 m/s²
Explanation:
The following data were obtained from the question:
Mass (m) of object = 40 Kg
Force applied (Fₐ) = 300 N
Force of friction (Fբ) = 30 N
Acceleration (a) =?
Next, we shall determine the net force acting on the mass. This can be obtained as follow:
Force applied (Fₐ) = 300 N
Force of friction (Fբ) = 30 N
Net force (Fₙ) =?
Fₙ = Fₐ – Fբ
Fₙ = 300 – 30
Fₙ = 270 N
Thus, the net force acting on the mass is 270 N.
Finally, we shall determine acceleration of the mass. This can be obtained as follow:
Mass (m) of object = 40 Kg
Net force (Fₙ) = 270 N
Acceleration (a) =?
Net force = mass × acceleration
Fₙ = m × a
270 = 40 × a
Divide both side by 40
a = 270 / 40
a = 6.75 m/s²
Therefore, the acceleration of the mass is 6.75 m/s²
A. Nebula . Is The Answer !
Answer:80kg/m^3
Explanation:
1L = 0.001m^3
25L= 25 *0.001 = 0.025m^3
Average density =mass/volume
Average density =2/0.025=80kg/m^3
