Explanation:
study of social sciencake us an effcient citizen of a democracy ,and it also help us to solve the practical problem in our daily life.
Answer:
Personally, I am sure that learning everything by looking at image is more effective than looking at a forest of letters. As for the field of science as human biology, it is very very important as well, because the illustrations are vital resource to convey important medical information that is easier to understand by showing it as a drawing rather than by only describing it with text.

Answer:
3.body
Explanation:
Both P and S waves are both body waves. Body waves are waves that travels through the earth.
P and S waves are elastic seismic waves that moves within the earth. Love and Rayleigh waves are surface waves that travels through the surface.
- P waves is also known as primary waves
- S waves are known secondary waves.
These waves are the first set of waves to arrive a seismic station before the surface waves are picked up.
Answer:
14.5 hours
Explanation:
The relationship between speed, time and distance for a uniform motion is
where
v is the speed
d is the distance
t is the time taken
Here we know:
v = 24.0 m/s is the average speed
is the distance
Solving the equation, we find the time taken:
And since
1 hour = 3600 s
The time in hours is
Answer:
OK draw a diagram - you have the force from (b) acting sown the slope and a component of the weight. Use F=ma to get the deceleration and then use SUVAT. Post your working if this doesn't work.
friction = 900N
braking = 3100N
total = 4000N
w= mxg = 1000*9.81= 9810N
total = 9810 + 4000 = 13810N
force/mass = 13810/1000 = 13.81ms^-2
then using v^2 = u^2 + 2as, i get s as 14 but it is incorrect
