Float. This is because water has a density of 1 g/ml, so anything less than this will float.
Answer:
This question is incomplete
Explanation:
This question is incomplete because of the absence of the time taken to complete one full cycle.
Frequency (<em>f</em>) will be calculated first as
<em>f </em>= <em>N </em>÷<em> t</em>
where <em>N </em>is the number of cycles and <em>t </em>is the time taken to complete one full cycle. The unit for frequency is Hertz (Hz).
To calculate the period, <em>T, </em>the formula below will be used
<em>T </em>= 1 ÷ <em>f</em>
The unit for period is secs
D. Energy that is transformed is neither destroyed nor created
Answer:
V₂ = 1.5 m/s
Explanation:
given,
speed of the first piece = 6 m/s
speed of the third piece = 3 m/s
speed of the second fragment = ?
mass ratios = 1 : 4 : 2
fragment break fly off = 120°
α = β = γ = 120°
sin α = sin β = sin γ = 0.866
using lammi's theorem
A,B and C is momentum of the fragments
4 x V₂ = 2 x 3
V₂ = 1.5 m/s
Answer:
2. False :
- An object that is positively charged has a greater positive charge and a lower negative charge.
3. Will be This :
Q.→ TRUE or FALSE: An object that is negatively charged could contain only electrons with <u>no</u> accompanying protons.
Answer → False :
- Negatively charged objects have protons; it's just their number of electrons is greater than their number of protons.
4. False :
- An object that is electrically neutral contains neutrons and the same number of unlike charges, i.e., electrons and protons.
