Answer:
6.79 m/s
Explanation:
By applying the principle of conservation of momentum.
The total momentum = MV - mv = 0 (since the squid is beginning at rest)
the mass of the squid (M) in absence of water in its cavity = (6.5 - 1.75) kg
= 4.75 kg
speed of the squid (V) = 2.5 m/s
mass of the water expelled (m) = 1.75 kg
speed of the water (v) = ???
∴
4.75 × 2.5 = 1.75 × v

v = 6.79 m/s
B. Warm air rises and takes heat with it; eventually it cools and sinks.
Explanation:
Warm air rising and taking heat with it which eventually cools and sinks describes a typical convection current. This is not radiation
Convection and radiation are both forms of heat transfer alongside conduction.
Radiation is the only form of heat transfer that does not involve the use of a medium or particles.
Air is a medium and it flouts the concept of heat transfer by radiation.
Convection is mostly taking place in fluids especially liquid and gas.

After my ythorough researching, the orbital velocity of the Earth compare to the Mercury is relative to each other. In addition, Mercury orbits the Sun and it is within the Earth's orbit as its lesser or inferior. The correct answer to the following given statement above is relative to each other.
Answer:

0.000439077936334 m
Explanation:
q = Charge of electron = 
E = Electric field = 
= Permittivity of free space = 
d = Distance between plates = 2 cm (assumed)
m = Mass of electron = 
The beam consists of electrons which means it has negative charge this means the upper plates will be positive and the lower plate will be negative.
The direction is upper to lower lower plate.
= Permittivity of free space = 
Electric flux is given by

The charge per unit area on the plates is 
Deflection is given by

The deflection is 0.000439077936334 m
