Answer:
= 0.331 J / g ° C
Explanation:
We have a calorimetry exercise where all the heat yielded by one of the components is absorbed by the other.
Heat ceded Qh = m1 ce1 (
-
)
Heat absorbed Qc = m2 ce2 ( - T₀)
Body 1 is metal and body 2 is water
. Where m are the masses of the two bodies, ce their specific heat and T the temperatures
Qh = Qc
m₁ (- ) = m₂ 
( - T₀)
we clear the specific heat of the metal
= m₂ ( - T₀) / (m₁ (-))
= 50.00 4.184 (20.15 -10.79) / (75.00 (99.0-20.15))
= 209.2 (9.36) / (75 78.85)
= 1958.11 / 5913.75
= 0.331 J / g ° C
Answer:
As You know kinetic Energy is equal (mv^2)/2
You can increase it by increasing the mass(keeping the velocity)
Or You can add velocity
Explanation:
Answer:
B
Explanation:
A solenoid is the wraps of conducting wire wrapped around the metal core .
it is easier to thrust a magnet into a wire coil with one loop than one with four loops Because with four loops it becomes more difficult to push the magnet in.
<h3>What is a magnetic field?</h3>
It is the type of field where the magnetic force is obtained. The magnetic force is obtained it is the field felt around a moving electric charge.
The quantity of turns or loops in a coil directly relates to the intensity of the magnetic field within the coil.
As a result, the magnetic field strength has increased fourfold when there are four loops instead of one, making it more difficult to push the magnet in.
A single-looped wire coil is simpler to insert a magnet into than one with four loops. because inserting the magnet gets more challenging when there are four loops.
