Answer: 10 m/s^2
Explanation:
1) The second law of Newton gives the definition and formula to calculate the net force:
Net force acting on an object = mass * acceleration.
2) From that, when you know the net force acting of the object and its mass, you can solve for the acceleration:
acceleration = Net force / mass
acceleration = 50 N / 5 kg = 10 m/s^2, which is the answer.
Answer:
The answer is
<h2>7,840,000 J</h2>
Explanation:
The kinetic energy KE of an object given it's mass and velocity can be found by using the formula

where
m is the mass
v is the velocity
From the question
m = 20000kg
v = 28 m/s
It's kinetic energy is

We have the final answer as
<h3>7,840,000 J</h3>

Explanation:
If you don't ventilate your boat after fueling, the gas fumes will stay in the bottom of boat and this is very dangerous.
Explosion can happen if you don't ventilate your boat after fueling so to avoid any explosion or any problem, you have to follow the proper procedure for fueling the boat.
So always ventilate your boat after fueling.
Answer : The correct option is, (D) 273 Kelvin, 0 degrees Celsius, 32 degrees Fahrenheit
Explanation :
Conversion of degree Celsius to Kelvin :

Conversion of degree Celsius to degrees Fahrenheit :

By using these two conversion factors, we get the three temperature readings all mean the same thing.
For option A :


For option B :


For option C :


For option D :


From the given options, only option (D) is correct.
Hence, the correct option is, (D) 273 Kelvin, 0 degrees Celsius, 32 degrees Fahrenheit
