Answer:
1/1000 or 0.001.
Step-by-step explanation:
10 ^-3
= 1/10^3
= 1/1000.
Answer:
The answer is 54.18 meters.
Explanation:
Fk = -mg + N cos (20) = 0
Fr = N sin (20) ( frictional force)
Fr = m (a) where as a = v²÷r
By putting in the values..
N = mg÷ cos (20)
r = v²÷ g tan (20) (radius equation)
= 13.89²÷ 9.81(tan 20) (gravitational force = 9.81 m/s²)
r = 54.18 meters.
Answer:
Step-by-step explanation:
4 I think not sure
Answer:
(a) 
(b) 
Step-by-step explanation:
Given
Solving (a): Multiply equation by 5.
Multiply both sides by 5
Open bracket
(b) Solve for y in and
Subtract 10x from both sides
Divide both sides by 35
Factorize the numerator:
Express 35 as 7 * 5
<em>When </em><em> is solved, the solution will be: </em><em></em>
