The core of the earth lets out radiation from under the ground which make the core responce of how volcano's errupt.
Answer:
The answer is D.
Explanation: The northern hemisphere is more cooler, because it doesn't have much sunlight to warm it up.
Answer:
3.67 km
Explanation:
Joe distance towards coffee shop is,

And the Max distance towards bookstore is,

Now the distance between the Joy and Max will be,
By applying pythagorus theorem,

Substitute 0.40 km for OB and 3.65 km for OA in the above equation.

Therefore the distance between there destination is 3.67 km.
Answer:
1.6 kg
Step-by-step Solution:
Since Force = mass × acceleration we have:
F = 8N
a= 5 m/s^2
m = ?
By plugging the values above into F=ma we obtain:

Therefore, the Chromebook has a mass of 1.6 kilograms.
Answer:
v = 0
Explanation:
This problem can be solved by taking into account:
- The equation for the calculation of the period in a spring-masss system
( 1 )
- The equation for the velocity of a simple harmonic motion
( 2 )
where m is the mass of the block, k is the spring constant, A is the amplitude (in this case A = 14 cm) and v is the velocity of the block
Hence

and by reeplacing it in ( 2 ):

In this case for 0.9 s the velocity is zero, that is, the block is in a position with the max displacement from the equilibrium.
