Answer:
t=2.14s
Explanation:
Since it asks us for the time it takes from the moment it starts accelerating, the first 5 seconds of movement mentioned is irrelevant here.
Next it'd be simple just to use the kinematic equation involving distance, time, and velocity:
∆d=V₀t+at²/2
From here we can move the change in distance over and use the quadratic formula to solve for time.

Answer:
The wavelength will be 4 cm, frequency will be 4.66 Hz and wave speed is 18.6 cm/sec
Explanation:
Given:
No. of crest = 13
No. of trough = 15
Time = 3 seconds
Hence, 1 crest or 1 trough =
therefore,
13 C + 15 T =
=
Time given 3 seconds
=
2 cm distance is travelled is time period
Again wave will travel in 1 T = 4 cm
wave speed v =
=
= 18.6 cm/s
Answer:
The answer is C.) Lacks all 3 types of antigens.
Answer:No
Explanation: Isolated systems are systems that exchanges no matter or energy with their surroundings. An equilibrium state of an isolated system has no natural tendency to change over time. If changes do occur in an isolated system, they continue until an equilibrium state is reached.
You okay? It is a tough time after the pandemic, and I hope you're all good :>
