Answer:
0.135 ms⁻²
Explanation:
By Newton's 2nd law,
The rate of change of momentum is directly proportional to the unbalance force applied on the object,
By that you can get the equation,
F = ma ⇒ a = F/m
where terms are in usual meaning
a = 125/925 = 0.135 ms⁻²
It seems that you have missed the given options for this question, but anyway, here is the correct answer. If humans cannot see ultraviolet waves, ultraviolet light can be used to gather evidence of a crime since u<span>ltraviolet light causes substances to fluoresce and give off visible light. Hope this is the answer that you are looking for. Thanks for posting!</span>
Answer:
Explanation:
Factors which affects and impacts our environment may include water, sunlight, buildings and so many other. The factors which can touched are called the physical factors. The physical factirs include buildings, humans and so on. Other factirs which aren't physical inckide the the effects posed to the environment t by biological and chemical factirs which may include, the impacts in sunlight and Rainfall, the pH and so on.
Answer:
M = 1.38 10⁵⁹ kg
Explanation:
For this problem we will use the law of universal gravitation
F = G m₁ m₂ / r²
Where G is the gravitation constant you are value 6.67 10⁻¹¹ N m2 / kg2, m are the masses and r the distance
In this case the mass of the planet is m = 3.0 10²³ kg and the mass of the start is M
Let's write Newton's second law
F = m a
The acceleration is centripetal
a = v² / r
The speed module is constant, so we can use the kinematic relationship
v = d / t
The distance remembered is the length of the circular orbit and the time in this case is called the period
d = 2π r
a = 2π r / T
Let's replace Newton's second law
G m M / r² = m (4π² r² / T²) / r
G M = 4 π² r³ / T²
M = 4 π² r³ / T² G
Let's calculate
M = 4 π² (3.0 10²³)³ / (3.4 10¹¹)² 6.67 10⁻¹¹
M = 13.82 10⁵⁸ kg
M = 1.38 10⁵⁹ kg
