Answer:
There are several possibilities why a battery can feel hot or heat up. In case of an external short circuit: this can happen when the battery is short circuited i.e. in a purse, or in a drawer. ... Then there is also the possibility of a short circuit, forced charging and heating up the battery.
Answer:
"The weight of an empty bottle is 10N...Calculate the mass of the empty bottle."
w=Weight; m=Mass; g=Gravity
w=mg
w/g=m
10/9.81=m
1.019368kg = m
Answer:
(a). The strength of the magnetic field is 0.1933 T.
(b). The magnetic flux through the loop is zero.
Explanation:
Given that,
Radius = 11.9 cm
Magnetic flux
(a). We need to calculate the strength of the magnetic field
Using formula of magnetic flux
Put the value into the formula
(b). If the magnetic field is directed parallel to the plane of the loop,
We need to calculate the magnetic flux through the loop
Using formula of flux
Here,
Hence, (a). The strength of the magnetic field is 0.1933 T.
(b). The magnetic flux through the loop is zero.
Answer:
The Kobe earthquake is 1.1 times more intense than the Northridge earthquake.
Explanation:
In order to answer the question, you have to calculate the rate of the two earthquakes, that way you will obtain how many times more intense was the Kobe earthquake compared to the Northridge earthquake.
The rate is obtained dividing the magnitude of the Kobe earthquake by the magnitude of the Northridge earthquake:
Rounding to one decimal place:
Rate=1.1
Let K and N represent the intensity of the Kobe and Northridge earthquakes, respectively. Therefore the rate can be written as:
The Kobe earthquake is 1.1 times more intense than the Northridge earthquake.
