Answer:
the process of finding the age of fossils is called carbon dating because they use samples of carbon and compare it's characteristics to the samples of carbon from each set time
Answer: Ф = 17.2657 ≈ 17°
Explanation:
we simply apply ET =0 about the ending of the rod
so In.g.L/2sinФ - In.a.L/2cosФ = 0
g.sinФ - a.cosФ = 0
g.sinФ = a.cosФ
∴ tanФ = a/g
Ф = tan⁻¹ a / g
Ф = tan⁻¹ ( 10 / 32.17405)
Ф = tan⁻¹ 0.31080948777
Ф = 17.2657 ≈ 17°
Therefore the angle of rotation of the rod during this acceleration is 17.2657 ≈ 17°
1)the edges where two plates meet are plate boundaries.
2)a sudden slip on a fault triggers an earthquake as stress in the edge overcomes the tension that releases energy into waves that move through the surface of the earth and cause a shake.
3)motion of the ground, aftershocks, shuddering, trembling, wobbling, crashing, falling, breaking, and more
4) the outer layer of Earth is the crust (lithosphere) which is made up of hot molten rock and granite.
On a speed/time graph, the height of the line at any point
shows the speed at that moment. If the line is horizontal,
then its height isn't changing, meaning that the speed isn't
changing. It's constant. The change is zero, until the line
starts rising or falling.
Answer:
735 J
Explanation:
Total height reached(displaced)=10x15 cm
= 10 x 15/100 m
= 1.5 m
Workdone = F.S (force x displacement)
Here, the boy is traveling against the gravitation force(=mg) , and traveled a height of 1.5m
Hence,
Workdone = 50 x 9.8 x 1.5 J
= 735 J
