How does time relate to motion
docker41 [41]
As we move, time goes up. Think of it on a graph; as time increases on the x axis, motion can either stay the same, increase, or decrease.

How do you find the voltage of a section of a parallel circuit?
sergiy2304 [10]

Answer: Voltage is the same across each component of the parallel circuit. The sum of the currents through each path is equal to the total current that flows from the source. You can find total resistance in a Parallel circuit with the following formula: 1/Rt = 1/R1 + 1/R2 + 1/R3 +.

Hope this helps!

An object has a mass of 12 kg. on planet a, the object weighs 69 n. the force of gravity on planet a is:_____.
balandron [24]

the force of gravity on planet a is g = 5.72 m/s2

There is an object that weighs 12 kg. The object's weight on Planet A is 69 N. The equation F=mg, where F is the weight, m is the mass, and g is the force of gravity, can be used to calculate the force of gravity on Planet A:

g = F/m

g = 69 N/ 12 kg

g = 5.72 m/s2

<h3>What is the gravity force?</h3>

The force of attraction between any two objects in the universe is known as gravity or gravitational force. The mass of the object and the square of the distance between them determine the force of attraction. The weakest known force in nature, it is by far.

A dog sees a flowerpot sail up and then back past a window 5.0 ft high. If the total time the pot is in sight is 1.0 seconds, fi
Kisachek [45]

To solve this problem we will use the linear motion kinematic equations for which acceleration (in this case gravity) is described as the change in velocity in an instant of time. Subsequently through the energy conservation equations we will find the net height.

Let's start considering that the time is 1 second, therefore,

t = 1s

Now the acceleration would be given as

g = \frac{\Delta v}{t}

g = \frac{v_f-v_i}{t}

v_f-v_i = gt

Since the final speed is zero, and the time elapsed to reach the height is 0.5 seconds (half of the entire route) we will have that the initial speed can be expressed in terms of gravity as

0-v_i = g(\frac{1}{2})

v_i = \frac{1}{2} g

Now for energy conservation, the potential energy must be equal to the kinetic energy, therefore,

PE = KE

mgh = \frac{1}{2} mv_i^2

h = \frac{v_i^2}{2g}

Replacing the previous value found,

h = \frac{1}{4} \frac{g^2}{2g}

h = \frac{1}{4} \frac{9.8^2}{2(9.8)}

h = 1.225m

Therefore the hegiht above the windows that the pot rises is 1.225m
