The Gamma Rays are the strongest. This would be located near the core of the sun. What makes ocean water the warmest depends on the season we are in. This is all due to the energy input into the sun.
Answer: it is rocket 2
Explanation: I just took the test
Hope it's the right answer for you
Explanation:
We need convert the velocities first to m/s and we get the following:
v2 = 21 km/hr = 5.8 m/s
v1 = 11 km/hr = 3.1 m/s
We need to find the mass of the car also for later use do using the work-energy theorem:
6.0x10^3 J = (0.5) m [(5.8)^2 - (3.1)^2]
or
m = 499.4 kg
Now we determine work needed delta W to change its velocity from 21 km/hr to 33 km/hr
v2 = 33 km/hr = 9.2 m/s
v1 = 21 km/hr = 5.8 m/s
delta W = (0.5)(499.4)[(9.2)^2 - (5.8)^2]
= 1.3 x 10^4 J
The acceleration of the wooden box is 6.17 m/s² towards the west.
<h3 /><h3>What is acceleration?</h3>
Acceleration can be defined as the rate of change of velocity.
To calculate the acceleration of the wooden box can be calculated using the formula below.
Formula:
- F₂-F₁ = ma.................. Equation 1
Where:
- F₂ = Force on the wooden box acting towards west
- F₁ = Force on the wooden box acting towards the east
- m = Mass of the wooden box.
- a = Acceleration of the wooden box
Make a the subject of the equation
- a = (F₂-F₁)/m........................ Equation 2
From the question,
Given:
- F₂ = 270.7 N
- F₁ = 85.7 N
- m = 30 kg
Substitute these values into equation 2
- a = (270.7-85.7)/30
- a = 185/30
- a = 6.17 m/s² towards the west.
Hence, The acceleration of the wooden box is 6.17 m/s² towards the west.

F = μN
Explanation:
Choose the normal force acting between the object and the ground. Let's assume a normal force of 250 N .
Determine the friction coefficient. ...
Multiply these values by each other: (250 N) * 0.13 = 32.5 N .
You just found the force of friction.
