Answer:
16,926
Explanation:
Q = mCΔT
Q = 30.0g × 45.5 × (45.5 - 32.1)
Q = 30.0 × 45.5 × 13.4
Q = 16,926
IMPORTANT NOTE:
Q = Heat
m = mass of sample
C = specific heat
ΔT = Change in temperature
Answer:
speed cannot be used to calculate the temperature
I think the answer is : Bobby exactly three years old today
to put it simply, absolute time can be perceived without depended to other object as comparison.
for example Evan is older than james is not an absolute time, because this conditions depend on the age comparison between the two subject
Answer:
a. It creates a pattern of alternating rock stripes on both sides of a mid-ocean ridge.
Explanation:
Seafloor spreading is the theory that the oceanic lithospheric plates are in constant motion just as continental drift occurs.
When oceanic plates collide, the denser subducts under the less dense one, causing a destruction of oceanic lithosphere.
However, during seafloor spreading, a rift in the ocean can spill out some of the partially melted subducted rock. When the magma cools, there is an alternation in the magnetic variation of rocks formed by the series of volcanic action that has occurred underwater.
The variation shows younger rocks closer to the mid-oceanic ridge formed in the process. This variation is measured and compared to confirm that sea floor spreading has actually occurred.
Answer:
The radius of the loop is 20.66 km
Explanation:
let the radius of the loop be r
mass of airplane is m
At the top, the pilot experiences two radial forces, which are
1) Gravitational force is mg
2) Centrifugal forces mv²/r out of the center
When the pilot experiences no weight,
then, mg = mv²/r
r = v² / g
= 450² / 9.8
= 20.66 x 10³3
= 20.66 km
