Answer:
Growth rate in micrometers per second is 3.05.
Given:
Growing length = 3.7 meter
Time = 14 days
To find:
Growth rate = ?
Formula used:
Growth rate =
Solution:
Growth rate =
Growing length = 3.7 × micrometer
Time = 14 × 24 × 60 × 60
Growth rate =
Growth rate = 3.05 micrometer per second
Growth rate in micrometers per second is 3.05.
To solve this problem we will apply the concepts related to energy conservation. Here we will understand that the potential energy accumulated on the object is equal to the work it has. Therefore the relationship that will allow us to calculate the height will be
Here,
m = mass
g = Acceleration due to gravity
h = Height
our values are,
Replacing,
Then the height is 32.83m.
Answer:
The chemical energy of the battery was reduced in 10800J
Explanation:
The first thing to take into account is that the stored energy in a battery is in Watts per second or Joules (). It means that the battery provides a power for a certain time.
The idea is to know how much has been consumed by the circuit.
The first step is to know the power that is consumed by the circuit. It is . The problem says that the circuit consumes a current of 5.0A with a voltage of 6.0V. It means that the power consumed is:
The previous value (30W) is the power that the circuit consumes.
Now, you must find the total amount of power that is consumed by the circuit in 6.0 minutes. You just have to multiply the power that the circuit consumed by the time it worked, it means, 6.0 minutes.
You must convert the minutes unit to seconds. Remember that 1 minute has 60 seconds.
Thus, the chemical energy of the battery was reduced in 10800J
Answer:
Explanation:
Given
Airplane is flying with horizontally with a constant momentum during time interval
Impulse is given by change in momentum, so there is no net impulse on the Plane because momentum is constant
(b) As there is no change in momentum therefore impulse of thrust and air drag is balanced i.e. both are equal in magnitude but act in opposite direction
