a wave that the medium is displaced perpendicular to the direction of the wave, such as waves on a string.
Explanation:
A transverse wave is a wave that the medium is displaced perpendicular to the direction of the wave, such as waves on a string.
A wave is a disturbance that transmits energy from one place to another.
There are two major types of waves:
- Transverse waves are waves that are propagated perpendicularly to the direction of the wave.
- A wave in string going up and down is a transverse wave.
- Electromagnetic waves are transverse waves.
- Seismic s-waves are transverse waves.
- Sound waves are longitudinal waves propagated parallel to their source.

Answer:
A is the answer as long as i can remember i was taught
I believe this would be an exothermic reaction, As time increases, the temperature goes up meaning the heat from the system is going into the surroundings. Which indicates an exothermic reaction.

<u>Answer:</u> The initial amount of Uranium-232 present is 11.3 grams.
<u>Explanation:</u>
All the radioactive reactions follows first order kinetics.
The equation used to calculate half life for first order kinetics:
We are given:
Putting values in above equation, we get:
Rate law expression for first order kinetics is given by the equation:
where,
k = rate constant =
t = time taken for decay process = 206.7 yrs
= initial amount of the reactant = ?
[A] = amount left after decay process = 1.40 g
Putting values in above equation, we get:
Hence, the initial amount of Uranium-232 present is 11.3 grams.
