Answer:
I know someone anwsered but it would be 400M
Explanation:
i initial velocity (u)=10m/s
acceleration (a)=0
time taken (t) =40s
then distance (s)=u t +1/2 a t^2
s= u t +0 (as a is 0)
s= 10 x 40
s= 400M
Answer:
B: beaks, finches.
Explanation:
Beaks, finches. This is because he noticed that fruit-eating finches had beaks similar to parrots, while finches that ate insects had narrow beaks. The difference in their beaks is due to adapting to different environments which causes them to evolve into different species of finches.
Answer:
2 gm/cm^3
Explanation:
The body is buoyed up by the amount of water is displaces
100 g is 100 cm^3 of water <===== this is the volume of the body
Density = mass/volume = 200 g / 100 cm^3 = 2 gm/ cm^3
The direction of the magnetic field around a wire depends on
the direction of the current flowing through the wire. When you
change the direction of the current in the wire, the direction of the
magnetic field around it also changes direction.
The current in every electric cord in your house changes its direction
120 times every second. So the magnetic field around every electric
cord in your house also changes its direction 120 times every second.
