Answer:
Stella is driving down a steep hill. She should keep her car in a lower gear to help slow her vehicle.
Explanation:
The potential energy of the egg when it begins to fall is equal to the kinetic energy of the egg just before touching the ground:
m * g * h = (1/2) * m * v ^ 2
Clearing the speed:
v = root (2 * h * g)
Substituting the values
v = root (2 * (10) * (9.8)) = 14
Then, by definition, we have
F * deltat = m * deltav
Clearing F
F = (m * deltav) / (deltat)
Substituting the values
F = ((0.060) * (14)) / (2) = 0.42
answer
the force exerted on the egg by the floor was 0.42N
The main cause of weather is uneven heating of the earth's surface.
There are various factors that contribute to weather, however the main factor is the uneven heating of the earths surface. This creates temperature differences and can cause water to evaporate and condense. This, combined with earth's spin lead to large scale weather systems and wind currents. These in turn are influenced by land forms, bodies of water, and even vegetation.
If an initial cardioversion attempt is unsuccessful in a 33-pound child, you should repeat the procedure using 30 joules.
Cardioversion
Cardioversion is a medical therapy that uses medications or electricity to restore a normal heart rhythm to someone who has an abnormally high heart rate (tachycardia) or another cardiac arrhythmia. Synchronized electrical cardioversion restores the activity of the heart's electrical conduction system by applying a therapeutic dosage of electric current to the heart at a specified point in the cardiac cycle. (Defibrillation is the most efficient form of resuscitation for cardiac arrest caused by ventricular fibrillation and pulseless ventricular tachycardia. It delivers a therapeutic dosage of electric current to the heart at an unpredictable point in the cardiac cycle. Chemical cardioversion, also known as pharmacologic cardioversion, substitutes antiarrhythmic drugs for an electrical shock.
