Answer: Option D

Explanation:

Global climate change can be defined as rise in temperature more than normal. This is the reason why many consequences of global warming can be seen.

The part of earth having maximum amount of ice is getting more heat and as a result of this ice is melting which increases the sea level more than 300 centimeters since 1880.

Thus, the correct answer is option D

D. Sea level has risen more than 300 centimeters. This is true because as the earth gets warmer, ice will melt and turn into water which goes into the ocean making it rise.

Starting from rest, a 5.00 kg steel sphere rolls down a frictionless ramp with a height of 4.00 m. What is the sphere's speed wh

elena-14-01-66 [18.8K]

Answer:

8.85437 m/s

Explanation:

m = Mass of sphere = 5 kg

h = Vertical height = 4 m

g = Acceleration due to gravity = 9.80 m/s²

Applying conservation of energy we get

$\dfrac{1}{2}mv^2=mgh$

$\\\Rightarrow v=\sqrt{2gh}$

$\\\Rightarrow v=\sqrt{2\times 9.8\times 4}$

$\\\Rightarrow v=8.85437\ m/s$

The sphere's speed when it reaches the bottom of the ramp is 8.85437 m/s

If light moves at a speed of 299,792,458 m/s, how long will it take light to move a distance of 1,000 km

astra-53 [7]

Answer:

change 1000km into Metre

1000km=1000000 M

speed= distance/time

time=distance/speed

time=1000000/299792458

time= 0.0033second

A bug is sitting on the edge of a rotating disk. At what angular velocity will the bug slide off the disk if its radius is 0.241

Ivahew [28]

Answer:

ω = 3.61 rad/sec

Explanation:

Firstly, we should know that the bug will not slip if friction can provide sufficient opposing force.

μmg = mv^2/r = mω^2r

Thus;

μg = ω^2r

ω^2 = μg/r

ω = √(μg/r)

ω = √(0.321 * 9.8)/0.241

ω = √(13.05)

= 3.61 rad/sec
