Answer:
19.6 N of torque. The 2kg load is being affected by acceleration due to gravity which is 9.8 m/s^s
Explanation:
2×9.8=19.6
Explanation :
The full form of laser is Light Amplification by Stimulated Emission of Radiation. It has particles of very high energy. It points in one direction.
Greg is giving a slide show presentation to a large audience. It is very important to make the presentation informative. By using a laser, we can focus on the important part of the presentation. So that we can highlight the important points.
Answer:
F = 19.375 x 10^-6 N
Explanation:
This problem can be solved by applying Coulomb's Law, which lets us determine the force between two electrically charged particles.
It is defined as
F = (ke * q1 * q2)/ r^2
Where,
ke = is Coulomb's constant ≈ 9×10^9 N⋅m^2⋅C^−2
q1 = 5.0 x 10^-8 C
q2 = 1.0 x 10^-7 C
r = 5 ft = 1,524 m
F = (9×10^9 N⋅m^2⋅C^−2)*(5.0 x 10^-8 C)*(1.0 x 10^-7 C)/ ((1,524 m)^2)
F = (9×10^9 N⋅m^2⋅C^−2)*(5.0 x 10^-8 C)*(1.0 x 10^-7 C)/ ((1,524 m)^2)
F = 19.375 x 10^-6 N
Answer:
is in units of 
is in units of 
is in units of 
Explanation:
We have the following expression:
Where:
is the distance, hence its unit is (meters, assuming we are using the International System of Units)
is the time, hence its unit is 
(seconds)
So, the expression is rewritten as:
Since the left side of the equation is in meters, the right side must be in meters as well.
In addition, in the right side we have terms that have to added, this means each term must be in meters:
- For the first term must be in units of in order to have meters.
- For the second term must be in units of in order to have meters.
- For the third term must be in units of in order to have meters.
Answer:
3.6m
Explanation:
if you are at a building that is 46m above the ground, and the professor is 1.80m, the egg must fall:
46m - 1.80m = 44.2m
the egg must fall for 44.2m to land on the head of the professor.
Now, how many time this takes?
we have to use the following free fall equation:
where 
is the height, 
is the initial velocity, in this case 
. 
is the acceleration of gravity: 
and is time, thus:
clearing for time:
we know that the egg has to fall for 44.2m, so 
, and , so we the time is:
Finally, if the professor has a speed of 
, it has to be at a distance:
and t=3.002s:
so the answer is the professor has to be 3.6m far from the building when you release the egg
