Answer:
Day when I workout I feel I have more energy, but on days when I don't I feel sluggish and tired
Answer:
When frequency increases more wave crests pass a fixed point each second. That means the wavelength shortens. So, as frequency increases, wavelength decreases. The opposite is also true—as frequency decreases, wavelength increases.
Explanation:
Answer:
25104 J
Explanation:
We are given;
Mass; m = 600 g
Change in temperature;Δt = (40 - 30) = 10°C
Specific heat of water; c = 4.184 J/g°C
Now, to find how many joules, we simply use the formula for quantity of heat.
Thus;
Q = mcΔt
Plugging in the relevant values to give;
Q = 600 × 4.184 × 10
Q = 25104 J
Quantity of heat = 25104 J
Answer:
velocity of this in the direction of the Earth is 6.4 × m/s
Explanation:
given data
wavelength = 121.6 nm
wavelength = 124.2 nm
solution
we get here first change in wavelength that is
= 124.2 nm - 121.6 nm ...............1
= 2.6 nm
we get here velocity of direction of the Earth that is express as
............2
put here value we get v
v =
v = 6.4 × m/s
