Answer:

Explanation:

TRISOMY 21 (NONDISJUNCTION)

Prior to or at conception, a pair of 21st chromosomes in either the sperm or the egg fails to separate. As the embryo develops, the extra chromosome is replicated in every cell of the body. This type of Down syndrome, which accounts for 95% of cases, is called trisomy 21.

<em>Down syndrome is a condition in which a person has an extra chromosome. Chromosomes are small “packages” of genes in the body. They determine how a baby’s body forms during pregnancy and how the baby’s body functions as it grows in the womb and after birth. Typically, a baby is born with 46 chromosomes. Babies with Down syndrome have an extra copy of one of these chromosomes, chromosome 21. A medical term for having an extra copy of a chromosome is ‘trisomy.’ Down syndrome is also referred to as Trisomy 21. This extra copy changes how the baby’s body and brain develop, which can cause both mental and physical challenges for the baby.</em>

When using a different calorimeter, and mixing 50 ml of hot water at 65 degrees c with 60 ml of water in the calorimete

Paha777 [63]

The specific heat capacity of the calorimeter used in mixing the water is determined as 21.87 J/g⁰C.

<h3>Conseervation of energy</h3>

The heat capacity of the calirometer is determined by applying the principle of conservation of energy.

Heat lost by the hot water = Heat gained by the calirometer

$Q _w = Q_c\\\\M_w C_w\Delta \theta _w = M_c C_c\Delta \theta _c$

where;

M is mass

mass = density x volume = ρV

Density of water = 1 g/ml

Mass of hot water = 1 x (50) = 50 g

Mass of water in calorimeter = 1 x (60) = 60 g

<h3>Equilibrium temperature</h3>

$\Delta T_c = 5.5\\\\T - 25 = 5.5\\\\T = 30.5 \ ^0C$

<h3>Specific heat capacity of the calirometer</h3>

$50 \times 4.184 \times (65 - 30.5) = 60 \times C_c \times (30.5 - 25)\\\\7217.4 = 330C_c\\\\C_c = \frac{7217.4}{330} \\\\C_c = 21.87 \ J/g^0C$

Thus, the specific heat capacity of the calorimeter used in mixing the water is determined as 21.87 J/g⁰C.

The complete question is below

When using a different calorimeter, and mixing 50 ml of hot water at

65 degrees C with 60 ml of water in the calorimeter at 25 degrees C, the temperature of the calorimeter increased by 5.5 degrees C.

a. Calculate the heat capacity of this calorimeter?

A parallel-plate capacitor is connected to a battery. The space between the two plates is empty. If the separation between the c

Maru [420]

Answer:

The final stored energy will become half.

Explanation:

We know that stored energy in the capacitor is given as

$E=\dfrac{1}{2}CV^2$

C=capacitance

V=Voltage difference

E=Energy

$C=\dfrac{\varepsilon A}{d}$

d=Distance between plates

A=Area

$E=\dfrac{1}{2}\times \dfrac{\varepsilon A}{d}\times V^2$

If the distance between plates get double ,say d' = 2 d

Then stored energy

$E'=\dfrac{1}{2}\times \dfrac{\varepsilon A}{d'}\times V^2$

$E'=\dfrac{1}{2}\times \dfrac{\varepsilon A}{2d}\times V^2$

$E'=\dfrac {E}{2}$

Therefore the final stored energy will become half.

A 40kg rock is perched atop a cliff that is 50 m high. What is it’s potential energy?

LekaFEV [45]

Potential energy, is energy due to its position.

Given: Mass m = 40 Kg; Height h = 50 m

Required: Potential energy P.E = ?

Formula: P.E = mgh P.E = (40 Kg)(9.8 m/s²)(50 m)

P.E = 19,600 J
