Answer:
D
Explanation:
One of the factors of increasing the rate of a reaction is increasing concentration. Therefore adding more people increases the number of people on the dance floor , therefore increasing the concentration increases the rate of reaction.
Answer:
(d) III only
Explanation:
We have to observe the motion of the bag with respect to taxi , considering taxi as stationary or inertial frame . Since bag is not moving with respect to taxi , the inertial frame that means , net force on it is zero .So option i and ii are ruled out .
Now how to explain motion of the bag ie why it is stationary ie what are the balancing force acting on it. We know that on a body on circular path , a force called centripetal force is acting on it . So that force must be acting on it . The balancing force is the frictional force which is keeping it stationary with respect to taxi . Hence the third option is correct.
Answer: The passage of a light wave can cause electrically charged particles to move up and down.
Explanation:
Electromagnetic waves are transversal waves, they are a combination of oscillating electric and magnetic fields, which propagate through space carrying energy from one place to another.
This means the oscillation of the wave occurs in the transversal direction to its propagation. In addition, electromagnetic waves are spread thanks to the electromagnetic fields produced by moving electric charges.
Which of what? Apologies please list the following so I can help.
