Answer:
Normal force, N = 154.5 N
Explanation:
Given that,
Total mass of the cart, m = 20.4 kg
Angle of inclination, 
Distance moved, d = 20.1 m
The coefficient of kinetic friction between ground and cart is 0.6
The value of acceleration due to gravity, 
Let N is the normal force exerted on the cart by the floor. It is given by :




T = 103.23 N
So, the normal force is :

N = 154.5 N
So, the normal force exerted on the cart by the floor is 154.5 N. Hence, this is the required solution.
Answer:
1.1259*10^9 Newton per Columb
Explanation:
the magnitude of the electric field intensity can be calculated using the expresion below;
E=Kq/r^2
Where k= constant
q= electric charge
r=distance= 2cm= 20*10^-2m( we convert to m for unit consistency
:,K=59*10^9 Columb
If we substitute the value into above formula we have
E=(9*10^9)*(5*10^-3)/(20*10^-2)^2
=1.1259*10^9 Newton per Columb
Therefore,the magnitude of the electric field intensity in vacuum at a distance of 20 cm is 1.1259*10^9 Newton per Columb
Most plastics have refractive indices in the range from 1.3 to 1.7, but some high-refractive-index polymers can have values as high as 1.76. For infrared light refractive indices can be considerably higher. Germanium is transparent in the wavelength region from 2 to 14 µm and has a refractive index of about 4.
Answer:
Power = 1471000[W]
Explanation:
In order to solve this problem, we must use the conversion factor of horsepower to Watts.
1 [Hp] → 735.5 [W]
Now using the conversion factor:
![2000[Hp]*\frac{735.5W}{1Hp}=1471000[W]](https://tex.z-dn.net/?f=2000%5BHp%5D%2A%5Cfrac%7B735.5W%7D%7B1Hp%7D%3D1471000%5BW%5D)
This might sound wrong, but it's right.
The electron microscope.
that is the answer
