If one m³ of that material holds 4,000 kg of it,
then 0.09 m³ holds
(0.09) x (4,000) = 360 kg of it
The force of gravity acting on 360 kg of anything
on the Earth's surface is
(mass) x (gravity)
= (360 kg) x (9.8 m/s²) = 3,528
A. All living things and objects
Answer:
Acceleration = 3m/s^2
Displacement = 126 m
Explanation:
The velocity changed from 12 to 30 m/s in 6 seconds. Using the formula for acceleration we get
(30-12)/6= 18/6= 3m/s^2
Displacement is d=.5a*t^2+v0*t
Inputting acceleration, time, and velocity leaves us with
d=1.5 * 36 + 12 * 6 = 54 + 72 = 126 m
Explanation:
Hi there!
Mass of the container (m) = 15000 kg
Also from the figure;
Volume of the container (V) = l*b*h
{ From figure length = 2m , breadth = 1.1m, height = 2.5m}
So,
V = (2*1.1*2.5) m³
= 5.5m³
Then;
Density (d) = m/v
= 15000/5.5
= 2727.27 kgm³
Therefore, the density is 2727.27 kgm³.
Hope it helps!
Answer: D. the distance between the highest points of consecutive waves
Explanation:
The wavelength of a wave is defined as the <em>distance traveled by a periodic perturbation that propagates through a medium in a given time interval</em>. It is usually represented by 
and can be calculated if the frequency of the wave is known, since there is an inverse relationship between both.
In the specific case of a periodic sine wave (which is the way in which a wave is usually represented graphically) the wavelength can be determined as the distance between two consecutive maxima of the disturbance.
Therefore, the correct option is D.
