Answer:
a)A= 3 m
b)
c)D= 15 m
Explanation:
Given that
v= 3 m/s
a)
The amplitude(A) of the pulse :
When x= 0 ,Then y = A
Put x= 0
y= A= 3 m
A= 3 m
b)
Distance travel in time t
x= vt
x= 3 t
c)
The distance covered by pulse in the time 5 s
D = v t
D= 3 x 5
D= 15 m
Answer: Skilled manpower is essential to carry out several development activities.

Answer:
Tides on our planet are caused by the gravitational pull of the Moon and Sun. Earth's oceans "bulge out" because the Moon's gravity pulls a little harder on one side of our planet (the side closer to the Moon) than it does on the other. The Sun's gravity raises tides, too, but lunar tides are twice as big.
Answer:
Yes
Explanation:
It is possible for sedimentary rocks to be converted to igneous rocks. Under conditions of high temperature and pressure, sedimentary rocks can be broken down into igneous rock by melting this rock type.
When the rock is broken down, it forms melt which when cooled and solidifies will form igneous rocks.
Sedimentary rocks are formed from the breaking down of pre-existing rocks through the action of weathering, erosion and sediment transportation. Within a basin, the sediments are compacted and lithified.
When this is subjected to intense pressure and temperature, the rock hardens and might further break down to melt.
It is possible to throw a 0.145 kg baseball much further than a 7 kg bowling ball, because the 0.145 kg baseball is of a smaller mass than the 7 kg bowling ball and it also offers less resistance to motion and hence it would go further than the 7 kg bowling ball.
