Answer:
KE=2.3 x 10⁻¹⁹ J
Explanation:
Given that
λ = 544 nm
λ' = 485 nm
The kinetic energy KE given as
KE= E - Ф
Where
h= 6.626 x 10⁻³⁴
C=3 x 10⁸ m/s
Now by putting the values
KE=2.3 x 10⁻¹⁹ J
This is kinetic energy.
Answer:
v = 4.76 m/s
Explanation:
Given,
The distance traveled by her bike, d = 10 miles
The time of her travel, t = 2.1 m/s
The velocity of an object is defined as the distance traveled by the object to the time of travel. Therefore,
V = d/t m/s
= 10 / 2.1
= 4.76 m/s
Hence, The velocity of her bike is, V = 4.76 m/s
The 50 W bulb would have a greater current than the 90 W bulb
Answer:
it should be changes in velocity
