Answer: Rr = 900w
T = 1.66×10^-5s
P = 36.92W
Explanation: please find the attached file for the solution.
Choice c) could represent the third step of inquiry.
Explanation:
Inquiry based learning is organized into inquiry phases.
The five general inquiry phase are
Orientation, conceptualisation, investigation, conclusion and discussion.
The investigation phase can be further divided into experimentation phase.
When Andrew washes three separate loads of dirty laundry ,one on hot setting,one one warm setting and one on cold setting , he is experimenting to collect data and interpreting it.
Only if he investigates will he know, which process will be suitable for doling out cleanest clothes.
Respuesta:
24m
Explicación:
Según la ecuación de movimiento
v = u + en
Dado
Velocidad final v = 12 m / s
velocidad inicial u = 0 m / s
tiempo t = 4s
Sustituir
12 = 0 + 4a
a = 12/4
a = 3 m / s²
Lo siguiente es obtener la distancia;
S = ut + 1 / 2at²
S = 0 (4) + 1/2 (3) (4) ²
S = 3 * 16/2
S = 48/2
S = 24 m
Por lo tanto, la distancia requerida es de 24 m.
Answer: The observing friend will the swimmer moving at a speed of 0.25 m/s.
Explanation:
- Let <em>S</em> be the speed of the swimmer, given as 1.25 m/s
- Let
be the speed of the river's current given as 1.00 m/s.
- Note that this speed is the magnitude of the velocity which is a vector quantity.
- The direction of the swimmer is upstream.
Hence the resultant velocity is given as, 
= S — S 0
= 1.25 — 1
= 0.25 m/s.
Therefore, the observing friend will see the swimmer moving at a speed of 0.25 m/s due to resistance produced by the current of the river.
