Answer:

The question can be re-framed as:

Heat:

⇒a) is the same as temperature

⇒b) can be increased by compression.

⇒c) is transferred in solids by conduction.

⇒d) is transferred in liquids by convection

⇒e) requires a medium.

Option c and d are correct choices.

Explanation:

⇔Heat is a form of energy which can be transferred from higher temperature to lower temperature.

So heat is not the same as temperature.

Where as temperature is the measure of Kinetic energy  possessed by the particles of an object.

⇔As far as the Ideal Gas Law is concerned any gas will tend to heat up as it is compressed and cool down when it expands.

Heat can't be increased by compression its transfer of energy.

⇔Conduction is the transfer of heat between substances that are in direct contact with each other.

Heat is transferred in solids by conduction.

⇔Heat is transferred from hot places to cold places by convection. Convection occurs when warmer areas of a liquid or gas rise to cooler areas in the liquid or gas.

Heat is transferred in liquids by convection.

⇔Heat does not requires a medium for its transfer as in case of radiation where heat is transferred by electromagnetic waves.

Heat doesn't requires a medium for its transfer.

So our correct answer comprises:

Option C and option D that is Heat "is transferred in solids by conduction" and "is transferred in liquids by convection".

The length of a simple pendulum is 0.66 m, the pendulum bob has a mass of 310 grams, and it is released at an angle of 12 degree
lina2011 [118]
A) the periodic time is given by the equation;
 T= 2π√(L/g)
For the frequency will be obtained by 1/T (Hz)
T = 2 × 3.14 √ (0.66/9.81)
   = 6.28 × √0.0673
    = 1.6289 Seconds
Frequency = 1/T = f = 1/1.6289
 thus; frequency = 0.614 Hz

b)  The vertical distance, the height is given by
 h= 0.66 cos 12
 h = 0.65 m
Vertical fall at the lowest point = 0.66 - 0.65 = 0.01 m
Applying conservation of energy
energy lost (MgΔh) = KE gained (1/2mv²)
 mgh = 1/2mv²
  v² = 2gΔh = 2×9.81 × 0.01 
                   = 0.1962
v = 0.443 m/s

c) total energy = KE + GPE = KE when GPE is equal to zero (at the lowest point possible)
Thus total energy is equal to;
E = 1/2mv²
   = 1/2 × 0.310 × 0.443²
   = 0.0304 J

Both speed and velocity measure how fast something is moving. However, since speed is not a _______ it does not require a(n )___
Arturiano [62]

Speed is different from velocity. Velocity is a vector quantity and has a direction. Speed is a scalar quantity and does not require a direction. The answer must be D).

A plant worker accidentally breathes some stored gaseous tritium, a beta emitter with maximum particle energy of 0.0186 MeV. The
andrey2020 [161]

Answer:

400 milli-rems

Solution:

As per the question;

Maximum energy of particle, E_{m} = 0.0186\ MeV

Weight, w = 1 kg

Energy absorbed, E = 4\times 10^{- 3}\ J

Now,

Equivalent dose is given by:

D_{eq} = \frac{E}{w}  =\frac{4\times 10^{- 3}}{1} = 4\times 10^{- 3}\ J/kg

1 Gy = 1 J/kg

Also,

1 Gy = 1\times 10^{5}\ milli-rems

Therefore,

Dose equivalent in milli-rems is given by:

D_{eq} = 4\times 10^{- 3}\times 1\times 10^{5} = 400\ milli-rems

Restate newtons first law of motion​
andriy [413]

Newton's first law of motion states that an object that is resting (not moving) will stay motionless unless an external force acts on it and an object in motion will stay in motion unless an outside force acts on it. This law is known as newton's law of inertia.
