Answer:
there are no provision to head it
Explanation:
because there are no oxygen
Answer:
625 N
Explanation:
The impulse given to the nail is equal to the change in momentum of the hammer:
where
F is the force exerted by the hammer
is the time of contact
is the mass
is the change in velocity of the hammer
Substituting the data and re-arranging the equation, we can find the force:
If I am to understand this question correctly this is what asks you:
If a person is riding a motorized tricycle how much work do they do?
You may ask yourself, why did I only use part of the question. Simple, the rest is not relevant to what is being asked. The weight, speed, and distance wont affect the person riding any <em><u>motorized vehicle</u></em> other than the time it takes to get from one place to another.
So to answer this question I would say:
Not much, all they really have to do is to steer and set the motorized tricycle to cruise control. Just like any rode certified vehicle.
If you have any questions about my answer please let me know and I will be happy to clarify any misunderstandings. Thanks and have a great day!
<u>Answer
</u>
4.8 A
<u>Explanation
</u>
From the ohm's law,
V = IR
where V is voltage, I is current and R is resistance.
I = V/R
= 12.0/2.5
= 4.8 A
Answer:
Explanation:
According to Newton 2nd law of motion: F = ma where m is the mass of the moon and a is the centripetal acceleration of the gravitational force.
Also Gravitational force formula
where G is the gravitational force, ME is the mass of Earth and S is the mean distance between Earth and Moon.
As the moon is at constant circular motion around Earth, there forces balance out:
We can now substitute 
and 
and
