Answer: Shield volcano is a broad, gently sloping, explosive volcano which is comprised of basaltic magma.
Shield volcano is normally not explosive but if somehow water comes in contact with this basaltic magma, then it turns into a more violent, explosive volcanoes, producing pyroclastic materials such as lapilli, lava bombs and block.
Answer:
D
Explanation:
F=ma
a=F/m
according to option D, F is constant
so acceleration is inversely proportional to mass and A has half the mass of B. Hence, acceleration of A will be twice of B if same force is applied.
We have to see the diagram luv
Answer:
No. Your friend will not hear the clap when he/she sees it.
Explanation:
It takes time for sound waves to go through a large area. It takes longer if people are in the area rather than it is empty.
Answer:
2 m
Explanation:
The following data were obtained from the question:
Time 1 = 3 s
Time 2 = 3.5 s
Velocity = 4 m/s (constant)
Displacement =?
Next, we shall determine the change in time. This can be obtained as follow:
Time 1 = 3 s
Time 2 = 3.5 s
Change in time = 3.5 – 3
Change in time = 0.5 s
Finally, we shall determine the displacement of the bird between 3 s and 3.5 s as follow:
Velocity = 4 m/s
Time = 0.5 s
Displacement =?
Velocity = Displacement /Time
4 = Displacement /0.5
Cross multiply
Displacement = 4 × 0.5
Displacement = 2 m
Therefore, the displacement of the birth between 3 and 3.5 s is 2 m.
