The scientific unit for speed is kilometers per hour, hope this helps
If one of two interacting charges is doubled, the force between the charges will double.
Explanation:
The force between two charges is given by Coulomb's law
K=constant= 9 x 10⁹ N m²/C²
q1= charge on first particle
q2= charge on second particle
r= distance between the two charges
Now if the first charge is doubled,
we get 
F'= 2 F
Thus the force gets doubled.
The tires deflated and so that means that you won’t be able to travel
If two different substances, with the same mass (1 gram) absorb the same amount of energy "the temperature of the substance with the lower specific heat will increase more than the one with a higher specific heat".
Option B
<u>Explanation:</u>
The thermodynamic function that specifies the amount of heat needed by one degree of temperature for a single unit of mass of a material to be elevated is understood as "Specific heat". Depending on the extent to which they absorb heat, various levels of specific heat values are seen for the materials.
The heat transferred relies on three factors: temperature change, weight of the device, material change and stage of the material. The average temperature of the molecules increases as the material heats up, so when they collide they are more likely to contribute enough energy to cause rotation and vibration to happen as the energy moves to a higher state.
