The planet closest to the sun; Mercury.
Answer:
Spectrophotometry is the quantitative measurement of light spectra reflection and transmission properties of materials as function of the wavelength. Photometry measures the total brightness as seen by the human eye

Please give me brainliest
Answer: 40
Explanation:60kg times 2 =120 pounds
power is 40
Answer:
4A
Explanation:
Current is charge per time. So if the second wire delivers twice as much charge in the same amount of time, it must have twice the current.
2 × 2A = 4A
Refer to the diagram shown below.
Neglect wind resistance.
g = 9.8 m/s².
Quantities are measured as positive upward.
When the ball is launched, it has a vertical velocity of - 3.5 m/s and a horizontal velocity of 25 m/s.
The time, t, for the ball to reach the ground is
(-3.5 m/s)*( t s) - 0.5*(9.8 m/s²)*( t s)² = - (270 m)
-3.5t - 4.9t² = - 270
4.9t² + 3.5t - 270 = 0
t² + 0.71433t - 55.102 = 0
Solve with the quadratic formula.
t = 0.5[-0.71433 +/- √220.918] = 7.0745 s or -7.788 s.
Reject negative time.
The horizontal distance traveled is
d = (25 m/s)*(7.0745 s) = 176.8625 m
Answer:
The horizontal distance from the girl to the ball will be 176.9 m (nearest tenth)
