The right half will be a new bar magnet of 2cm with north pole on the right side and south pole on teh left.
Hey there!
1.) Without the atmosphere, average temperature on Earth would be freezing! Below zero to be exact!
2.) The atmosphere protects us and animals from dangerous radiation from the Sun. Ultraviolet radiation is basically invisible rays of energy created by the sun.
3.) Also, the atmosphere provides oxygen for humans and animals to breathe and C02 (Carbon dioxide) for plants.
4.) And lastly, the atmosphere protects us from objects coming towards the earth.
Hope this helps!
Positive acceleration occurs when an object speeds up.
Explanation:
Acceleration is the rate of change in velocity per unit time:
where 
is the change in velocity while 
is the time interval. From the formula, we can understand that when is positive, so when the object is speeding up, the acceleration is positive; on the contrary, when is negative (so, when the object is slowing down), the acceleration is negative.
A battery running to a transistor to regulate voltage to then power an LED lightbulb.
To solve the problem it is necessary to apply the concepts related to the conservation of linear Moment, that is to say
Where,
m = Mass
v = Velocity
P = Linear momentum
For the given data we have to:
The components of this force would be given by,
According to the definition given at the end of the problem, this component corresponds to that expressed for x and y.
Applying the previous equation we have,
<em>Note: The component at this direction must also decomposed</em>
The mass is 143g=0.143kg, then:
Therefore the final vector is:
