Answer:
57.885.8 kg weight of the container
Explanation:
The volume of the balloon * density of water = buoyant force of balloon
volume of a sphere = 4/3 pi r^3
= 4/3 pi * (1.5)^3 = 14.14 m^3 <===balloon volume
Now, find the buoyant force on the container ALONE ....
5.8 * 2.6 * 2.8 * 1027 = 43 364 kg <===== buoyant force
Now add the buoyant force of the balloon to find the weight
43 364 + 14.14 * 1027 = 57885.8 kg
Answer:
Explanation:
log10 function is required to convert dB into intensity of a sound. Both are measures of loudness of a sound and the relationship can be expressed as follows:
dB = 10 log10(I/Io), where Io is 10^-12 W/m^2
Substituting, 82 = 10 log10(I/10^-12)
I = 0.0001585 W/m^2
or 1.58*10^-4 W/m^2
Answer:
an infective agent that typically consists of a nucleic acid molecule in a protein coat, is too small to be seen by light microscopy, and is able to multiply only within the living cells of a host.

The potential energy of the block is A) 490 J
Explanation:
The potential energy of an object is the energy possessed by the object due to its position in the gravitational field.
It is calculated as follows:
where
m is the mass of the object
g is the acceleration due to gravity
h is the height of the object above the ground
For the block in this problem, we have:
m = 10 kg
h = 5 m
Therefore, its potential energy is:

let each runner starts from rest
v₀ = initial velocity of each runner = 0 m/s
t = time of travel = 2 sec =
a = average acceleration
average acceleration is given as
a = (v - v₀)/t
inserting the values
a = (v - 0)/t
a = v/t
since each runner gains equal amount of speed in given time interval of "t". hence the average acceleration of each runner is same.
