Explanation:
Given that,
Magnitude of electric field in +x direction, E = 4.9 V/m
Part A :
The relation between electric and magnetic field is given by :
c is the speed of light
So, the magnetic field of the wave at this same point in space and instant in time is .\
Part B :
The direction of electric and magnetic field is same i.e. +x direction.
Hence, this is the required solution.
c
Immediately upon reaching its lowest point, a falling pendulum bob has its greatest amount of kinetic energy, which is less than the initial amount of potential energy.
remember the law of energy there cannot be any more since it is using the potential energy to move
Answer:
H₂0_{(s)} + heat → H₂O(l)
Explanation:
An ENDOTHERMIC reaction is a chemical reaction in which heat is absorbed by the reactants. As such the product is usually cooler than the products. In the equation above (the answer), heat is on the reactant side of the equation thus indicating that heat is absorbed by the reactants.
On the other hand, in the first equation heat is on the product side of the equation which is consistent with an Exothermic reaction.
Have a good day♥
Answer:
Explanation:
The melting point of the solid is 80°C
Vapor point of the liquid is 140°C
What happens to particles of X when heated from 70°C to 85°C?
- Firstly, there would be a phase change from solid to liquid.
- Below the melting point, a substance will exist as a solid.
- With increase in thermal energy inputted by heat, as the temperature climbs above the melting point, it changes to the liquid.
- When the solid begins to heat up, the particles of X starts vibrating about their fixed point.
- At they melting point, they break lose and flow to form a liquid.
- The particles will have more kinetic energy.
Answer:
It means that if force is constant, as mass is increased, acceleration decreases
