No it does not because this weight is being balanced by a normal source
Answer:
v = 1.6 m/s
Explanation:
Given that,
Distance, d = 72 m
Time taken, t = 45 s
We need to find their average velocity. Average velocity of an object is given by total distance divided by total time taken.
So, their average velocity is 1.6 m/s.
Explanation:
Volume is the amount of space an object takes up, while mass is the amount of matter in an object. ... To find the volume of an irregular sized object, one would use the displacement method for measuring volume and place the object in water and measure the amount of water that is displaced.
Answer:
Option 3
Explanation:
O Option C is NEGATIVELY CHARGED, meaning it has GAINED ELECTRONS resulting in a GREATER number of ELECTRONS than PROTONS.
The energy of light for a single photon that has a wavelength of 347 nm is 5.698 × 10-¹⁹ J
HOW TO CALCULATE ENERGY:
- The energy of a photon of light can be calculated by using the following formula:
E = hf
Where;
- E = energy of photon (J)
- h = Planck's constant (6.626 × 10-³⁴J/s)
- f = frequency (Hz)
- However, the frequency must first be calculated using the formula as follows:
λ = v/f
Where;
- λ = wavelength
- v = speed of light (3 × 10⁸m/s)
- f = frequency
- E = 6.626 × 10-³⁴ × 8.6 × 10¹⁴
- Therefore, the energy of light for a single photon that has a wavelength of 347 nm is 5.698 × 10-¹⁹ J.
