The most common liquid on planet earth is water
Answer:

Given:
Initial speed (u) = 22 m/s
Final speed (v) = 0 m/s (Rest)
Time taken (t) = 4 seconds
To Find:
Distance travelled by car (s)
Explanation:
From equation of motion of object moving with uniform acceleration in straight line we have:

By substituting value of v, u & t in the equation we get:


Distance travelled by car (s) = 44 m
Answer:
The elements carbon and oxygen form molecules that each contain one carbon atom and two oxygen atoms is TRUE.
Explanation:
The elements carbon and oxygen form molecules that each contain one carbon atom and two oxygen atoms is true because a compound can only be formed from the combination of two or more elements but not from one element.
The molecule formed from one carbon element (C) and 2 oxygen elements (O) is CO2. CO2 which is known as carbon(IV)oxide is a compound which is made up of carbon and oxygen elements.
Answer:
Answer is (C)
Explanation:
<u>For</u><u> </u><u>acceleration</u>
• If the motion is vertically, then acceleration is 9.8 m/s²
» Upward motion, acceleration is negative (-9.8)
» Downward motion, acceleration is positive (+9.8)
<u>For</u><u> </u><u>velocity</u>

Answer: F = 2.1 x 10^-4N
Explanation: Question is incomplete.
The complete question is; A straight, 2.5-m wire carries a typical household current of 1.5 A (in one direction) at a location where the earth’s magnetic field is 0.55 gauss from south to north. Find the magnitude and direction of the force that our planet’s magnetic field exerts on this wire if it is oriented so that the current in it is running (a) from west to east.
Given parameters; l = 2.5m, I = 1.5A, B = 0.55 guass = 0.55 x 10^-4 Tesla , theta = 90 (from West to East), F = ?
F = BILsin(theta)
F = 0.55 x 10^-4 x 1.5 x 2.5 x sin 90
F = 2.1 x 10^-4 N.
According to right hand rule, it's direction is upward.
