In  making a thermometer used to monitor the temperature of the water, a glass tube, a scale, and a thermometric liquid such as alcohol is required.

<h3>What is a thermometer?</h3>

A thermometer is an instrument that is used to measure or read the temperature of a body or a substance.

There are different types of thermometers such as:

  • Liquid-in-glass thermometers
  • Gas thermometers
  • Resistance thermometers

A simple liquid-in-glass thermometer consists of the following parts:

  • A glass tube
  • A scale
  • A thermometric liquid such as alcohol

Therefor, in making a thermometer used to monitor the temperature of the water, a glass tube, a scale, and a thermometric liquid such as alcohol is required.

In conclusion, a thermometer is the instrument used in measuring temperature.

Some plants disperse their seeds when the fruit splits and contracts, propelling the seeds through the air. The trajectory of th
Anton [14]

Answer:

Option B, 93 cm

Explanation:

An diagram of the seed's motion is attached to this solution.

This is very close to a projectile motion question. And the quantity to be calculated, how far along the grant a seed released would travel is called the Range.

And this would be obtained from the equations of motion,

First of, the height of the plant is related to some quantities of the motion with this relation.

H = u(y) t + 0.5g(t^2)

U(y) = initial vertical component of velocity = 0 m/s, H = height at which motion began, = 20cm = 0.2 m

That means t = √(2H/g)

The horizontal distance covered, R,

R = u(x) t + 0.5g(t^2) = u(x) t (the second part of the equation goes to zero as the vertical component of the acceleration of this motion is 0)

(substituting the t = √(2H/g) derived from above

R = u(x) √(2H/g)

Where u(x) = the initial horizontal component of the bomb's velocity = maximum initial speed, that is, 4.6 m/s, H = vertical height at which the seed was released = 20 cm = 0.2 m, g = acceleration due to gravity = 9.8 m/s2

R = 4.6 √(2×0.2/9.8) = 0.929 m = 0.93 m = 93 cm. Option B.

Five-gram samples of copper and aluminum are at room temperature. Both receive equal amounts of energy due to heat flow. The spe
hammer [34]

Answer:

  • <u><em>c. The copper will get hotter than the aluminum.</em></u>

Explanation:

The <em>energy due to heat flow</em>, i.e. the heat energy, is proportional to the product of the mass, the <em>specific heat capacity</em>, and the change in <em>temperature</em>:

          Heat=mass\times \text{specific heat capacity }\times\Delta T

From which you obtain:

     \Delta T=\dfrac{Heat}{mass\times \text{specific heat capacity}}

That equation tells that the change in temperature is inversely related to the product of the mass and the specific heat.

In the problem, the masses of the samples of copper and aluminum are equal (<em>5.00g</em>) and both samples receive <em>equal amounts of energy due to heat flow</em>, thus the only difference is the <em>specific heat capacity</em> of each sample.

From the above stated relationship between the change in temperature, the heat, the mass, and the specific heat capacity, under the assumption of all the other conditions equal (heat energy and mass), the higher the specific heat capacity the lower the change in temperature, and the lower the specific heat capacity the greater the change in temperature.

The heat capacity of copper (0.09 cal/g°C) is lower than the specific heat capacity of aluminum is (0.22 cal/g°C), thus the increase in temeperature of the copper sample will be greater than that of the aluminum sample. This means that <em>the copper will get hotter than the aluminum (option c.)</em>

How does speed affect momentum
Arada [10]
Momentum = mass • velocity
M = m • v

Speed is a scalar quantity
Velocity is a vector quantity

That is truly the only difference
