Answer:

The winter solstice occurs around Dec 21 and the earth will still be cooling even tho after this time the days are getting longer.

The earth will not experience warming until sometime later and the heat received equals the heat radiated.

This is similar to ice age occurrences.

The earth can be warming, but it will take considerable time until the heat received exceeds the heat lost.

A 0.0750kg teddy bear is dropped from a deck that is 3.00m above the ground. What will be the velocity of the teddy bear as it s

FrozenT [24]

The velocity of the teddy bear as it strikes the ground is 7.67 m/s.

<h3>Velocity of the teddy when it strikes the ground</h3>

The velocity of the teddy when it strikes the ground is calculated from principle of conservation of energy as shown below.

K.E(bottom) = P.E(top)

¹/₂mv² = mgh

v² = 2gh

v = √2gh

where;

h is height of fall of the teddy
g is acceleration due to gravity

v = √(2 x 9.8 x 3)

v = 7.67 m/s

Thus, the velocity of the teddy bear as it strikes the ground is 7.67 m/s.

As a dilligent physics student, you carry out physics experiments at every opportunity. At this opportunity, you carry a 1.39-m-

grin007 [14]

Answer:

The strength of magnetic field is $6.21 \times 10^{-5}$ T

Explanation:

Given:

Length of rod $l = 1.39$ m

Velocity $v = 3.37$ $\frac{m}{s}$

Induced emf $= 0.291 \times 10^{-3}$ V

According to the faraday's law

Induced emf = $Blv$

We have to find strength of the magnetic field,

$B = \frac{0.291 \times 10^{-3} }{1.39 \times3.37}$

$B = 6.21 \times 10^{-5}$ T

Therefore, the strength of magnetic field is $6.21 \times 10^{-5}$ T

A student used apparatus as shown above. The beaker held 750 g of a liquid. The current from the power supply was 1.8 A and the

liq [111]

Answer:

$2365.71\ \text{J/kg}^{\circ}\text{C}$

Explanation:

V = Voltage = 230 V

I = Current = 1.8 A

$\Delta T$ = Temperature change = $(40-12)^{\circ}\text{C}$

t = Time taken = 2 minutes

m = Mass of liquid = 750 g

c = Specific heat capacity of the liquid

Energy required to heat the water is equal to the heat released due to current passing

$mc\Delta T=VIt\\\Rightarrow c=\dfrac{VIt}{m\Delta T}\\\Rightarrow c=\dfrac{230\times 1.8\times 2\times 60}{0.75\times (40-12)}\\\Rightarrow c=2365.71\ \text{J/kg}^{\circ}\text{C}$

The specific heat capacity of the liquid is $2365.71\ \text{J/kg}^{\circ}\text{C}$
