Answer:
All organisms begin their lives as single cells.Overtime,these organisms grow and take on the characteristics of their species...All organisms grow,and different parts of organisms may grow at different rates.Organisims made out of only one cell
may change little during their lives, but they do grow

Answer:
A. Using
Fl= ( v+vl/v+vz)fz
= (340+19/340+31) x 2020
= 1954.7Hz
Then to find the frequency of sound when reflected from the truck such that the driver becomes the listener
we use
F"= ( v+vz/v+vl) fz
= 340+31/340+19 x 2020
2087.5Hz
B to find the wavelength of sound we use
Wavelength= V+vl/ F"
= 340+31/2087.5= 0.18m
Answer:
<h2>To find the resultant force <u>subtract the magnitude of the smaller force from the magnitude of the larger force.</u> The direction of the resultant force is in the same direction as the larger force. A force of 5 N acts to the right, and a force of 3 N act to the left. Calculate the resultant force.</h2>
Answer:
because the mass of the apple is very less compared to the mass of earth. Due to less mass the apple cannot produce noticable acceleration in the earth but the earth which has more mass produces noticable acceleration in the apple. thus we can see apple falling on towards the earth but we cannot see earth moving towards the apple.
As we can see here the lever has two forces at two ends
1. 300 N
2. 200 N
now we need to find the Torque on the lever about the fulcrum
so we will have
1. clockwise torque due to force at right end is
2. counterclockwise torque due to force at left end
so as per above calculations we can see that net torque on the lever is clockwise as it has more torque in clockwise direction
so <u>it will rotate clockwise</u>
