Answer:
2m/s
Explanation:
The formula for acceleration can be found by [ a = f/m ]
We are given the force [ 100N ] and the mass [ 50g ].
We can use these values to solve for the acceleration.
a = 100/50
a = 2m/s
Best of Luck!
The total amount of mass in the Sun is 2.0 x 10^30 kg, 5% of whig is hydrogen, and 13% of which becomes available for fusion. Thus, the total mass of hydrogen available for fusion over the Sun's lifetime is simply 13% of 75% of the total mass of the Sun or:
2.0 x 10^30 kg x .75 x .13
=<u> 1.95 x 10^29 kg</u>

Nuclear fusion occurs only in the core of the sun where temperature pressure and density are highest. The photosphere can be seen with visible light telescopes, the chromosphere with ultraviolet telescopes, and the corona most easily with X-ray telescopes.
The Sun is a typical star and also the closest star to the Earth. It is composed of 73% hydrogen, 25% helium, and 2% other elements. Since the gravitational pull of the sun on the earth is the centripetal force that causes the earth to move in a circular motion around the sun, we can use Newton's law of universal gravitation to find the mass of the sun without visiting it.

Answer:
Explanation:
Force on q due to Q
= k Qq / ( a² + d²)
x component
= k Qq / ( a² + d²) x d /√ ( a² + d²)
F = kQq d/ ( a² + d²)³/²
differentiating F with respect to d
dF / Dd = kQq [ d. -3/2 ( a² + d²)⁻⁵/² 2d + ( a² + d²)⁻³/²]=0 for maximum F
- 3d² / ( a² + d²) + 1 = 0
a² + d² = 3 d²
a² = 2d²
d = a / √2
Answer:
IV because the process of water is equal to 5,8 to 783253.23 to the hendroxagram of 4.
Explanation:
Answer:
The magnitude of force is 571.2 N.
Explanation:
Given data :-
i) Mass of the box = 84 kg.
ii) Frictionless surface means friction force is zero.
iii)The force ( F ) which act on box = m*a.
iv) The time for which the box is in motion ( t ) = 5 seconds.
v) The distance traveled by box ( S ) = 85 meter.
Now to find magnitude of force we have to calculate the value of acceleration.
We know the equation of motion.
S = (u*t )+0.5 (a*t²)
85 = 0 + 0.5 * a *5² ( u = initial velocity = 0 )
a = 6.8 m²/s.
∴ F = m*a = 84 * 6.8 = 571.2 N
