Answer:
λ = 4.2x10^-13 m
Explanation:
c = λν
c is speed of light 3x10^8 m/s
λ is wavelength
ν is frequency
3.10^8 = λ . 7.13 × 10^20
λ = 4.2x10^-13 m
Answer:
sorry but dorks dont learn maths
Explanation:
just kidding no offense but i think umm 1st one will stay same
i searched google
C. because i take college classes and I've did this before
Answer: 10 ml of 200 mM is required and 30 ml of water is required.
Explanation:
According to the dilution law,
where,
= concentration of stock solution = 200mM
= volume of stock solution = ?
= concentration of resulting solution= 50mM
= volume of another acid solution= 40 ml
Thus 10 ml of 200 mM is required and (40-10) ml = 30 ml of water is to be added to make 40 ml of 50mM .
The third launch ( with 300 N force) had the greatest acceleration of the tennis ball
<h3>Further explanation </h3>
Newton's 2nd law explains that the acceleration produced by the resultant force on an object is proportional and in line with the resultant force and inversely proportional to the mass of the object
∑F = m. a
F = force, N
m = mass = kg
a = acceleration due to gravity, m / s²
From the above equation it has been shown that the force acting on the object is directly proportional to its acceleration, so <em>the greater the force exerted on the object, the greater the acceleration of the object produced.</em>
