Answer:
2 seconds
Explanation:
The function of height is given in form of time. For maximum height, we need to use the concept of maxima and minima of differentiation.

Differentiate with respect to t on both the sides, we get

For maxima and minima, put the value of dh / dt is equal to zero. we get
- 32 t + 64 = 0
t = 2 second
Thus, the arrow reaches at maximum height after 2 seconds.
Answer:
Light is shown through air on a diamond n=2.42) and it partially reflects and reflects.
Based on the incident angle of 62.5 shown what is the angle of reflection of the light
question of options
21.5
To solve the problem, start by applying the concepts related to current in an RL circuit. The current is defined exponentially and using Ohm's law we can put the initial current in terms of the voltage and resistance. Consecutively with the calculated time constant we can find the respective inductance. For the second part we will apply the electrical potential energy connectors to find the amount of stored energy.
PART A)





Inductance can be defined then,



PART B) Now the energy is given under the terms:



Therefore the energy stored in the coil at this same moment is 0.0002727J
Answer:
That would be a molecule. : )
Explanation:
The definition of a molecule is a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.
