Answer:

D) the universal law of gravitation.

Explanation:

Based on the statement of the Coulomb's law, it is easy to conclude that the law is similar to the universal law of gravitation.

Newton's law of universal gravitation is one of the most interesting physical laws out there.

It states that "the gravitational force of attraction between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distances between the charges".

Recalling the coulomb's law, we can clearly see that both shows a direct proportionality of force to quantity of charges/mass and inverse proportionality to the square of the distances between them.

Answer:

The initial speed of the water droplets is approximately 14.904 meters per second.

Explanation:

We can describe the water jet from archerfish as part of parabolic motion, which consists of the superposition of two different motions. First, an horizontal motion at constant velocity and, second, a free fall motion. The maximum height is reached when vertical component of speed is zero. The equation of motion is described below:

v^{2} = v_{o}^{2}\cdot \sin^{2} \theta + 2\cdot g \cdot (y-y_{o})

Where:

v_{o} - Initial speed of the water jet, measured in meters per second.

v - Current speed of the water jet, measured in meters per second.

g - Gravitational acceleration, measured in meters per square second.

y_{o} - Initial height, measured in meters.

y - Current height, measured in meters.

Now we clear the initial speed within equation:

v_{o}^{2} =\frac{v^{2}-2\cdot g\cdot (y-y_{o})}{\sin^{2}\theta}

v_{o} = \sqrt{\frac{v^{2}-2\cdot g\cdot (y-y_{o})}{\sin^{2}\theta} }

If we know that v = 0\,\frac{m}{s}, g = -9.807\,\frac{m}{s^{2}}, y = 10\,m, y=0\,m and \theta = 70^{\circ}, the initial speed of the water droplets is:

v_{o} = \sqrt{\frac{\left(0\,\frac{m}{s} \right)^{2}-2\cdot \left(-9.807\,\frac{m}{s^{2}} \right)\cdot (10\,m-0\,m)}{\sin^{2}70^{\circ}} }

v_{o} \approx 14.904\,\frac{m}{s}

The initial speed of the water droplets is approximately 14.904 meters per second.

Consider an alcohol and a mercury thermometer that read exactly 0 oC at the ice point and 100 oC at the steam point. The distanc
Alexeev081 [22]

Answer:

No, both the thermometers will give the different reading.

Explanation:

Given,

  • Both thermometer has same ice point = T_i\ =\ 0^o C
  • Both thermometer has same steam point = T_s\ =\ 100^o C
  • Distance between the ice point and steam point in both the thermometer is same of 100 division,

All the data given in both the thermometers are same, but the material in the thermometer is different due to this the reading at 60^o C will differ in both the thermometer. Because the reading on both the thermometer is depended upon the thermal expansion of the material inside it, but both the materials are different. Due to this the rise of fluid in the thermometer, i,e,. the volume of the fluid material in the thermometer will depend upon the thermal expansion.  Hence both the material alcohol and mercury have the different thermal expansion, therefore the rise of the fluid in the thermometer also differ in both the thermometer.
