Mass of the Earth = 5.972 x 10²⁴ kg
Mass of the asteroid = 1 x 10⁹ kg
Separation distance = 3 x 10⁶ m (between the Earth's center and the asteroid's center)
Gravitational force between two masses =
(6.67 x 10⁻¹¹ nt-m²/kg²) · m₁ · m₂ / (distance)²
= (6.67 x 10⁻¹¹ nt-m²/kg²) · (5.972 x 10²⁴ kg) · (1 x 10⁹ kg) / (3 x 10⁶ m)²
= (6.67 · 5.972 / 9) x 10¹⁰ · (nt · m² · kg · kg / kg² · m²)
= 13.28 x 10¹⁰ newtons
= 132.8 Giga-newtons .

Answer:
Velocity of proton will be equal to 4500 m/sec
Explanation:
We have given that proton moves right angles through a magnetic field
So angle between magnetic field and velocity of proton is
Magnetic field B = 0.025 Tesla
Charge on proton
Magnetic force on the proton is given
Magnetic force on a moving charge particle is equal to
So
v = 4500 m/sec
So velocity of proton will be equal to 4500 m/sec
ISOTOPES (C) are atoms with the same number of protons, but different numbers of neutrons.

Answer:
The approximate displacement of the object is <u>23 </u>m.
Explanation:
Given that:
v = 4t + 5 (m/s) for 3< t< 7; n= 4
The approximate displacement of the object can be calculated as follows:
The velocities at the intervals of t are :
3
4
5
6
the velocity at the intervals of t = 7 will be left out due the fact that we are calculating the left endpoint Reimann sum
n = 4 since there are 4 values for t, Then there is no need to divide the velocity values
v(3) = 4(3)+5
v(3) = 12+5
v(3) = 17
v(4)= 4(4)+5
v(4) = 16 + 5
v(4) = 21
v(5)= 4(5)+5
v(5) = 20 + 5
v(5) = 25
v(6) = 4(6)+5
v(6) = 24 + 5
v(6) = 29
Using Left end point;
= 23 m
