It’s either Asia or the America
Answer:
4.29 millimeters
Explanation:
Bats emit ultrasound waves: in air, ultrasound waves travel at a speed of
The frequency of the waves emitted by this bat is:
Therefore we can find the wavelength of the wave emitted by the bat by using the relationship between speed, frequency and wavelength:
Troposphere. The troposphere is the lowest layer of our atmosphere.
Stratosphere. The infamous ozone layer is found within the stratosphere.
Mesosphere. Most meteors burn up in the mesosphere.
Thermosphere. Many satellites actually orbit Earth within the thermosphere
Exosphere. Considered to be the actual "final frontier"
Ionosphere. The electrically charged atoms and molecules that are formed in this way are called ions, giving the ionosphere its name
Answer:
Charge
Explanation:
Unit of ampere is defined as the coulomb of charge per unit time which is in seconds.
Here, i is in ampere, qis the charge which is in coulomb, and the t is in sec which is time.
Therefore,
Charge=ampere-second.
Therefore, the unit ampere-second will represent the charge.
Answer:
Explanation:
If a rocket (firework) is launched
with an initial velocity of 39.2 meters per second at a height of 1.6 meters above
the ground, the equation h = -4.9t2
+ 39.2t + 1.6 represents the rocket’s height h in
meters after t seconds. The rocket will explode at approximately the highest point.
Fire official require the fireworks to explode at a height greater than 76 feet in
order for debris to land in Lake Michigan and not on the festival sight. The event
planners assured the fire officials that the fireworks would reach a height greater
than 76 feet
