Answer:
a) 10 dB, b) 20dB, c) 10², 10⁴, 10⁸
Explanation:
The logarithmic scale has a great advantage when measuring magnitudes of a large number of scales, since it converts these values to linear, allowing easier viewing.
Part A
Let's look for decibels for an intensity I = 10 Io
We calculate
β = 10 log (10Io / Io)
β = 10 dB
Part b
Let's find the intensity for I = 100 Io
We calculate
β = 10 log (100Io / Io)
β = 10 log 100
β = 10 2
β = 20 db
Part c
Δβ2 corresponds to an intensity change of 10² Io, therefore it corresponds to an intensity increase of 10²
Δβ4 corresponds to a change in intensity of 10⁴Io
Δβ8 is an intensity change of 10⁸ Io
WITHOUT air resistance . . . like on the moon, or in a tank with all
the air removed from it . . . a feather, an orange, and a watermelon
will all fall at the same rate.
So will a piece of tissue, a mosquito, school bus, a rock, and a cruise
ship.
If you drop them all at the same time, then they will all hit the ground
at the same time.
Answer:
It is not correct.
The correct conversion is:
1030 KJ = 246.18 KCal.
Explanation:
To know if 1030 KJ is equivalent to 245 KCal, we shall convert 1030 kJ to kcal. This can be obtained as follow:
4.184 KJ = 1 KCal
Therefore,
1030 KJ = 1030 KJ × 1 KCal / 4.184 KJ
1030 KJ = 246.18 KCal.
Thus, 1030 KJ is equivalent to 246.18 KCal.
From the above calculation, we can see that:
1030 KJ ≠ 245 KCal
Rather,
1030 KJ = 246.18 KCal.
C. you need to double your speed.
since there is gravity and the more mass the more gravity pulls it to the core of the earth; cars are heavy.
As the mass of jupiter is more than the mass of earth it has a greater graviationsl force in it........as we know that our weight depends on mass of object and thr gravitational force on it......if the gravitational force is increased the object's weight will definitely increase......
Due to more mass of jupiter than earth it means that there are more forces acting on every single point where mass acts......if these points are more the gravitational force will also increase.......
HOOE IT HELPED !!!!
