Answer:
Rocket 2 has highest acceleration.
Explanation:
Net force,
F = mass (m) × acceleration (a)
We have,
m₁ = 4.25 kg and F = 120 N
m₂ = 3.25 kg, F₂ = 120 N
m₃ = 5.5 kg, F₃ = 120 N
m₄ = 4.5 kg, F₄ = 120 N
Hence, it can be seen that the highest acceleration is of rocket 2.
Answer:
5010 m
Explanation:
The vertical position of the teacher at time t can be found by using the equation:
where
h is the initial height
is the initial velocity (negative since it's downward)
is the acceleration of gravity
t is the time
The teacher reaches the ground when y = 0, so the equation becomes
Substituting t = 30 s, we find the initial height:
Answer:
Explanation:
As per the spectrum range, it is important to observe the Sun and other astronomical objects from Earth's surface because they lie in the visible band of spectrum.
Earth's atmosphere absorbs ultraviolet light coming from the space thus helps us to know and learn about their properties.
If we place telescope in space, would be covered with water droplets thus making it useless to study about any object or to see them hence proper place such as Earth's atmosphere is well suited to observe stars and other celestial bodies.
Variables shift both the long-run and short-run aggregate-supply curves are productivity, labor Wage Costs and taxes and other costs.
<h3>What is aggregate-supply?</h3>
The entire quantity of goods and services that enterprises in a national economy intend to sell during a certain time period is known as aggregate supply
Variables shift both the long-run and short-run aggregate-supply curves are ;
1. Productivity
2. Labor Wage Costs.
3. Taxes and other costs -
4. Material Prices.
5. Size of labor force.
6. Stock of Capital.
Hence, variables shift both the long-run and short-run aggregate-supply curves are productivity, labor Wage Costs and taxes and other costs.

Answer:
b a model of water temperatures in the oceans
Explanation:
A conceptual model is a means of representing abstract theories, with the aim of helping the audience form mental pictures about the subject being discussed. Most of these models utilize diagrams to help form a better understanding of the subject.
In geothermal explorations, water temperatures can be represented using plane or cross sectional views to demonstrate the varying temperatures of water. This is a useful guidde in the exploration proceess and helps any who read the illustrations to form a better understanding of the process and conditions.
