Answer:
Explanation:
In our universe the unit of current used to be defined as the current that produces a certain force per unit of length between two wires separated by a certain length. This means:
Replacing force by its definition
And since current is charge over time
From this we can define length as a function of time, mass, and charge:
<span>The temperature of water will boil at one hundred degrees celsius when the external pressure is at 17.5 torr. Essentially, it is based off of the vaporizing of heat, as well as the gas constant. This is a matter of solving a physics equation and breaking down the factors that will affect the boiling point.</span>
Answer:
<h3>The answer is 3.37 m/s²</h3>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
From the question
force = 172 N
mass = 51 kg
We have
We have the final answer as
<h3>3.37 m/s²</h3>
Hope this helps you
Answer & Explanation:
This can be explained with Newton's first law, Inertia - if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
When you walk, your entire body is in a forwarding motion. If your toe hits an object (in this case, a chair), only this unfortunate toe will stop while the rest of your body continues its forwarding motion, resulting in you falling forward.
Acceleration = (change in speed) / (time for the change)
Change in speed = (speed at the end) - (speed at the beginning)
= (140 km/hr) - (10 km/hr) = 130 km/hr
Time for the change = 50 sec
Acceleration = (130 km/hr) / (50 sec) = 2.6 km/hr per second.
To convert to more familiar units:
(2.6 km/hr-sec) x (1000 m/km) x (1 hr/3600 sec)
= (2.6 x 1000 x 1) / (3600) km-m-hr / hr-sec-km-sec
= 0.722 m/s² (about 0.074 of a G)
