Water is a great conductor of electricity. True or False
Answer:
False
Explanation:
Think about every warning on electrical products, which is 'DO NOT KEEP NEAR WATER'
Answer:
FALSE
Explanation:
Pure water is not a good conductor of electricity. ... Because electrical current is carried by ions in solution, conductivity increases as the ion concentration increases. In such a way, that the conductivity when water dissolves ionic compounds.

A meteor moving through space speeds up as it gets closer to Earth. What force causes the meteor's speed to increase the closer it gets to Earth?
PLS Help
Answer:
gravity
Explanation:
its hard to explain its one of the resons we do gravity assists for space probes and such the meteor will catch earths gravity and be pulled in by it if you look at sednas orbit as it gets closer to the sun it speeds up.
The force that causes the meteor's speed to increase as it gets closer to Earth is the gravitational force of earth.
What is meant by gravity ?Gravity is defined as the force by which a planet attracts another body towards its center.
Here,
The meteor was moving through space and the speed of the meteor started increasing as it moves closer to the earth.
This is because of the gravitational force of earth that is being exerted on the meteor. Gravitational force of earth is defined as the force of attraction that the earth exerts on another body in its gravitational field and draws them towards the center of the earth.
As the meteor moves towards the earth's , it gets accelerated by the earth's gravitational field such that the speed of the meteor increases and thus it attains more kinetic energy. As a result, the meteor moves faster when it gets closer to earth. This is because of the force of gravity of the earth.
Hence,
The force that causes the meteor's speed to increase as it gets closer to Earth is the gravitational force of earth.

The weight of a cuboid box is 288 N. Find its mass.
Answer:
29.39 kg
Explanation:
From the question,
W = mg...................... Equation 1
Where W = weight of the cuboid box, m = mass of the cuboid box, g = acceleration due to gravity.
make m the subject of the equation
m = W/g.................. Equation 2
Given: W = 288 N
Constant: g = 9.8 m/s²
Substitute these values into equation 2
m = 288/9.8
m = 29.39 kg

A spiral staircase winds up to the top of a tower in an old castle. To measure the height of the tower, a rope is attached to the top of the tower and hung down the center of the staircase. However, nothing is available with which to measure the length of the rope. Therefore, at the bottom of the rope a small object is attached so as to form a simple pendulum that just clears the floor. The period of the pendulum is measured to be 8.5 s. What is the height of the tower
Answer:
L = 17.94 m
Explanation:
The angular velocity of a simple pendulum is
w = [tex]\sqrt{ \frac{g}{L} }[/tex]
the angular velocity is related to the period
w = 2π / T
we substitute
[tex]\frac{4\pi ^2 }{T^2} = \frac{g}{L}[/tex]
L = [tex]\frac{g T^2}{4 \pi ^2}[/tex]
let's calculate
L = 9.8 8.5² / 4π²
L = 17.94 m

The velocity of a car increases from +4.0 m/s to +16.0 m/s
in a time period of 4.0 s. What was the average
acceleration?
Answer:
Explanation:
Although we do have an equation for this in terms of one-dimensional motion, it's easy enough just to use the mathematical definition of acceleration:
[tex]a=\frac{v_f-v_0}{t}[/tex] which says, in words, the acceleration of an object is equal to the objects final velocity minus its initial velocity, divided by the change in time. Since everything is given in m and s, our answer will be in m/s/s:
[tex]a=\frac{16.0-4.0}{4.0}[/tex] and
[tex]a=\frac{12.0}{4.0}[/tex] so
a = 3.0 m/s/s
