6. An excited dog runs full-speed toward his owner who has just returned home from
school. If he runs north along their driveway for a distance of 45 m and takes 5.2 s to get
there, what is his average velocity?
Please answer in comments with work !!:)
Answer:
v = 8.65 m/s
Explanation:
Given that,
Distance covered by the doge, d = 45 m
Time taken, t = 5.2 s
We need to find its average speed. The total distance covered divided by the total time taken is called the average speed of an object. So,
[tex]v=\dfrac{45\ m}{5.2\ s}\\\\=8.65\ m/s[/tex]
So, the average speed is 8.65 m/s.

In the oxygen cycle, oxygen is
(Choose one):
1.) added to and removed from the atmosphere by photosynthesis.
2.) added to the atmosphere by cellular respiration and removed by photosynthesis.
3.) added to the atmosphere by decomposers and removed by photosynthesis.
4.) added to the atmosphere by photosynthesis and removed by cellular respiration and combustion.
Answer:
4.) added to the atmosphere by photosynthesis and removed by cellular respiration and combustion.
Explanation:
The atmospheric cycle is a biogeochemical cycle and is a transition between the oxidation state in ions, oxides, and molecules. The largest reservoir on the earth for oxygen island or lithosphere. The crust and mantle together make up 99.5% of oxygen by volume. The rest is found in the air that 21%, 22% in the biosphere, and 33% in the hydrosphere.Two 1.2 kΩ resistors are in series and this series combination is in parallel with a 3.3 kΩ resistor. The total resistance is

A transformer has 100 turns on primary coil and 300 turn on secondary coil. If 20V Ac is applied to the primary coil, what would be the secondary voltage?
Answer:
the secondary voltage is 60 V.
Explanation:
Given;
number of turns on the primary coil, Np = 100 turns
number of turns on the secondary coil, Ns = 300 turns
voltage supply in the primary coil, Vp = 20 V
let the secondary voltage = Vs
Apply the following transformer equation to determine the secondary voltage;
[tex]\frac{V_s}{V_p} =\frac{N_s}{N_p} \\\\V_s = \frac{V_p \times N_s}{N_p}\\\\V_s = \frac{20 \times 300}{100} \\\\V_s = 60 \ V[/tex]
Therefore, the secondary voltage is 60 V.
Measuring a liquid's volume indicated the capacity ______ of the holds it. The most common units for expressing liquid volumes are _____ and milliliters.
Answer:
Measuring, comparing and estimating liquid volumes are taught using metric units like liters and milliliters and customary units like quart, pints, gallons and more. Capacity is actually the amount of liquid in the container, which is also the volume of a liquid.

When the forces acting on a stationary object are unbalanced, the object will
A. remain stationary
B. begin moving and speed up
C. remain moving at a constant speed
D. No effect
Answer:
B
Explanation:
Well it is certainly not no effect. Something has to happen. Not D.
If the balances are unbalanced it means that there is a force left over that can cause an acceleration. The speed is not constant when there is an acceleration. Not C
Unbalanced forces mean that there has to be something happening. Unless the friction cannot be overcome, there will be motion. Not A. But it is your second best answer if there is friction.
The answer I think you are intended to give is B.
A point charge at the origin of a coordinate system produces the electric field E=(56,000 N/C) x on the x-axis at the location x=-0.65m. Determine the sign and magnitude of the charge.
Answer:
q = 1.95 x 10⁻⁶ C = 1.95 μC
Explanation:
The formula for the electric field produced by a point charge is given as follows:
[tex]E = \frac{kq}{r^2}\\[/tex]
where,
E = Electric Field strength = 56000 N/C
k = Colomb's Constant = 9 x 10⁹ Nm²/C²
q = magnitude of charge = ?
r = distance = 0.65 m
Therefore,
[tex]56000\ N/C = \frac{(9\ x\ 10^9\ Nm^2/C^2)q}{(0.56\ m)^2}\\\\q = \frac{(56000\ N/C)(0.56\ m)^2}{9\ x\ 10^9\ Nm^/C^2}\\\\[/tex]
q = 1.95 x 10⁻⁶ C = 1.95 μC

I'm contrast to Venus the coldest temperature yet measured on the surface of any body in the solar system is -235C
Answer:
Explanation:
I don't get what the relation here is. Venus is the hottest planet in our solar system. And yes, it's hotter than mercury despite mercury being closer to the sun. And your question talks about the coldest temperature measured which is -235 degrees Celsius. That surely isn't measured on Venus. I'm only wondering what Venus has got to go with cold and what exactly your question is

The weight of the fluid that an object displaces is equal to the buoyant force acting on the object is
spring force
Archimedes Principle
buoyant force
Hooke's Law
Answer:
Archimedes' Principle
Explanation:
Its because Archimedes' Principle states "that the buoyant force on an object is equal to the weight of the fluid displaced by the object.... If you want to know the buoyant force on an object, you only need to determine the weight of the fluid displaced by the object."

The current at 5.0 V is
A.
The current at 15 V is
A.
Answer:
A. Recall Ohm's Law: V = IR
If V = 45 volts, and I = 5 amps, the R = V/I = 45V/5A = 9Ω
B. We know the potential difference and the resistance, both of which have good units. All we have to do is plug the known values into the equation and solve for the current:
I=15V9Ω
Thus, the electric current is: 1.67A
