Answer:
This statement is false.
Explanation:
If the farmers field is close to the stream, and has experienced a lot of runoff, the runoff will carry chemicals from the farm into the stream, which includes fertilizers among other chemicals. This runoff into the stream will not lead to a decrease in the level of fertilizers in the stream. Therefore, one of the effect of this cannot be a decrease in the level of fertilizers from the field.
It is B
When we look at a red apple, it's absorbing colors from the sunlight. It absorbs all the colors of the rainbow—except for red. The red light reflects off the apple and our brain and eyes work together to let us know what color we are seeing.
Answer:
Final speed, v = 12.57 m/s
Explanation:
Given that,
Slope with respect to horizontal, 
Distance travelled, d = 19 m
Initial speed of the cyclist, u = 9.5 m/s
We need to find the final speed of the cyclist. Let h is the height of the sloping surface such that,
h = 3.46 m
Let v is the final speed of the cyclist. It can be calculated using work energy theorem as :
v = 12.57 m/s
So, the final speed of the 12.57 m/s. Hence, this is the required solution.
Answer:
T = 15,576 N
Explanation:
The speed of a wave on a string is given by
v = √ T /ρ rho
also the speed of the wave is given by the relationship
v = λ f
we substitute
λ f = √ T /ρ
T = (lam f)² ρ
let's find the wavelength in a string, fixed at the ends, the relation that gives the wavelength is
L= λ/2 n
λ= 2L / n
we substitute
T = (2L / n f)²ρ rho
let's calculate
T = (2 1.20 / 2 590) 0.022
T = 15,576 N
