Answer:
Explanation:
magnetic field B = (3 i + 8 x 2 j )x 10⁻³ T
= (3 i + 16 j )x 10⁻³ T
L = - i ( unit length of conductor )
Force F = I ( L x B ) , I is current
= 5 [ - i x ( 3i + 16 j ) 10⁻³]
= 5 ( - 16 k ) x 10⁻³
F = - 80 x 10⁻³ k
The incident ray will have an angle of reflection of 30 degrees (made with a surface normal to the mirror surface). The reflected ray will make an angle of 60 degrees (90 - 30 degrees) with the mirror surface.
The answer is: 12.30 degrees.
To solve this problem you must apply the proccedure shown below:
1. You run 22 meters horizontally and then you climb a rope vertically for 4.8 meters.
2. So. let's call the angle 
, therefore, you must find it using 
, as following:
3. Substitute values and solve for the angle:
Answer:
vast amounts of plant life that existed before dinosouars. Fossil fuels are fuels such as natural gas, coal, petrol, et cetera which are formed naturally by the decomposition of remains of dead plants and animals.
Explanation:
That statement is true.
the capacitor is initially uncharged, but starts to charged when the switch is closed.
The potential difference across the resistor will steadily dropped as the potential difference across the capacitor increased.
