a) It can dissolve other substances and has high specific heat capacity.
b) Pressure is transferred equally in all directions
c) F=14*0.04/0.02=28 N
d) I'd expect that it will sink cause weight will pull it to the bottom
e) Because the buoyant force is stipulated by difference between pressures in the top and bottom surfaces of a body.
f) Because this force increases in denser liquids: 
, where rho is density.
g) Q=Av, where v - speed, A - area. With the same flow rate v=Q/A, so larger area decreases speed and vice versa.
Answer:
Explanation:
Each time the work done to raise a given mass is
here we know that
now we have
since it is just 25% of actual energy consumed as we know its efficiency is 25%
so we have total energy consumed in this way
now if it took N number of times so burn the fat of a pizza then
The wavelength of a standing wave is 8.13 m.
<h3>What is a wavelength?</h3>
The distance between two successive troughs or crests is known as the wavelength. The peak of the wave is the highest point, while the trough is the lowest.
The wavelength is also defined as the distance between two locations in a wave that have the same oscillation phase.
The given data in the problem is;
String length(L)= 48.8 metere
Wavelength(λ)=?
The length of the wave having n nodes is found as;
L=nλ
Substitute the given value;
48.8 = 6λ
λ= 8.13 m
Hence, the wavelength of a standing wave is 8.13 m.

b
Explanation:
Mass number consist of number of proton and neutron in an atom
Answer:
10 kg
Explanation:
The question is most likely asking for the mass of the bicycle.
Momentum is the product of an object's mass and velocity. Mathematically:
p = m * v
Where p = momentum
m = mass
v = velocity
Hence, mass is:
m = p / v
From the question:
p = 25 kgm/s
v = 2.5 m/s
Mass is:
m = 25 / 2.5 = 10 kg
The mass of the bicycle is 10 kg.
In case the question requires the Kinetic energy of the bicycle, it can be gotten by using the formula
K. E = ½ * p * v
K. E. = ½ * 25 * 2.5 = 31.25 J
