An empty 50-g bowl rests on a scale that measures force (in newtons). Water is then poured into the scale from a height of 0.50

m and rate of 10 mL/s. Assuming that the water does not splash as it comes to rest, calculate the reading on the scale at t = 5.0 s

Answer:

1 Newton

Explanation:

Mass of bowl (Mb) = 50 g = 0.05 kg

Initial Velocity (Vo) = 10 mL/s = 10g/s

time (t) = 5.0s

Mass of water (Mw) = 10 g/s * 5s = 50 g = 0.05 kg

*Vob = initial velocity of bowl

*Vow = initial velocity of water

*Vf = final velocity

*g = gravity = 9.8

<u>Conservation of momentum [Inelastic Collision]:</u>

  • (m1)(Vo1) + (m2)(Vo2) = (M1+M2)Vf
  • <u>(</u>Mw)(Vow) +  (Mb)(Vob) = (Mw+Mb)Vf
  • (50g)(10g/s) + (50g)(0) = (50g + 50g)(Vf)
  • Vf = 500/100 = 5g/s = 0.005kg/s

<u>Impulse-Momentum Theorem:</u>

  • Δp = mΔv

<u>Scale Reading:</u>

  • Δp + Mw(g) + Mb(g)
  • = (0.05kg + 0.05kg)*(0.05kg/s) + (0.05kg*9.8) +(0.05kg*9.8)
  • = 0.9805 = 1 Newton

Maggie is using her cat in an experiment on animal intelligence. Which of the following statements is true?
Kamila [148]

1. If Maggie gives her cat an unfair advantage, her experimental results will be biased.

Explanation:

Maggie using her cat in the experiment to test for intelligence gives the cat an unfair advantage, her experimental results will be biased.

  • Due to her emotional attachment with the cat, the experimental results will be skewed to portraying her cat as intelligence.
  • This is not a good experiment to carry out.
  • Such an experiment should be carried out with an unknown cat.

2. The convex mirror shown below has an object placed 15cm in front of it. An image is formed 35 cm
Elena-2011 [213]

Answer:

m = image distance/object distance

m=35/15=7/3

f=uv/(u+v)

35*15/(35+15)

f=10.5cm

Each gene controls the production of one or more specific ( Blank).
konstantin123 [22]

Answer:

Genes are located in the CHROMOSOME

Explanation:

Genes are contained in chromosomes, which are in the cell nucleus. A chromosome contains hundreds to thousands of genes. Every normal human cell contains 23 pairs of chromosomes, for a total of 46 chromosomes. A trait is any gene-determined characteristic and is often determined by more than one gene.

A racecar driver on a flat racetrack steps on the gas, changing her velocity from 10 m/sec to 30 m/sec in 5 seconds. What is the
erastova [34]

Answer:

4m/s2

Explanation:

The following data were obtained from the question:

U (initial velocity) = 10m/s

V (final velocity) = 30m/s

t (time) = 5secs

a (acceleration) =?

Acceleration is the rate of change of velocity with time. It is represented mathematically as:

a = (V - U)/t

Now, with this equation i.e

a = (V - U)/t, we can calculate the acceleration of the race car as follow:

a = (V - U)/t

a = (30 - 10)/5

a = 20/5

a = 4m/s2

Therefore, the acceleration of the race car is 4m/s2
