The force of gravity is the
force with which massively large objects such as the earth attracts another
object towards itself. All objects of the earth exert a gravity that is
directed towards the center of the earth. Therefore, the force of gravity of
the earth is equal to the mass of the object times acceleration due to gravity.
F = ma
4.9N = m (9.8 m/s^2), note that
N (newtons) = kg-m/s^2
<u>m = 0.5 kg</u>
<u>The mass of the object is
0.5kg.</u>
<span>I of disk = 1/2MR² = (0.5)(230)(4.0)² = 1840 kgm²
I of disk-woman system = I = 1/2MR² + md² = (50)(4.0)² = 1840 + 800 = 2640 kgm²
L = Iw = (2640)(0.80)(2π) = 13,270 ≈ = 13,000 kgm²/s ANS
idk I'm just trying</span>
Answer:
V = 152.542 volts
Explanation:
Given data:
area of plates
distance between the plates is 
charge = 
we know that capacitance is given as
potential difference is given as
V = 152.542 volts
Answer:
c. 
Explanation:
= Initial distance between asteroid and rock = 7514 km = 7514000 m
= Final distance between asteroid and rock = 2823 km = 2823000 m
= Initial speed of rock = 136 ms⁻¹
= Final speed of rock = 392 ms⁻¹
= mass of the rock
= mass of the asteroid
Using conservation of energy
Initial Kinetic energy of rock + Initial gravitational potential energy = Final Kinetic energy of rock + Final gravitational potential energy
Answer:
correct is option c I'm sure
