Answer:
108 extended days
Explanation:
Regular school hours a day = 6 hr
No. of school days to make up by extending the regular hours = 3 days
Amount of time added to the regular hours of school = 10 min
No. of extended school days to make up the 3 school days by following the above mentioned criteria be x.
Time of school hours in 3 days = 
are required to make up 3 days of school having 6 hours of regular timing with 10 minutes of add-on time each day.
Answer:
1000m/s
Explanation:
velocity(v)=momentum(p)/mass
=100/.1
=1000m/s
You use a force meter to measure newtons
Answer:
The answer is 
<em> pounds</em>
Explanation:
We will start this question by representing the force vectors in Cartesian coordinate system:
- Force 1 acting on the right
- Force 2 acting upward
- Force 3 acting at 45°
Let the single force we need be represented by 
Since, the body is in equilibrium the summation of all the forces acting on it should be zero:
∑
(Sum of all forces in 
direction is equal to zero)
( component of force 3 is negative because it is acting in opposite direction)
∑
(Sum of all forces in 
direction is equal to zero)
( component of force 3 is negative because it is acting in opposite direction)
So,
Hence, to get the scalar quantity of a single force:
![F=\sqrt[2]{(0.1213)^{2}+(-2.8786)^{2} }](https://tex.z-dn.net/?f=F%3D%5Csqrt%5B2%5D%7B%280.1213%29%5E%7B2%7D%2B%28-2.8786%29%5E%7B2%7D%20%20%7D)
<em> pounds</em>
To determine the energy equivalent of an object, we use the famous equation of Einstein which is E=mc^2 where m is the mass of the object and c is the speed of light (3x10^8 m/s). We calculate as follows:
E = mc^2
E = 1.83 kg (3x10^8 m/s)^2
E = 1.647x10^17 J
