The uneven gamete division causes chromosomal abnormalities.
What is a Gamete?A gamete is a fully developed reproductive or sex cell with haploid chromosomes that has the capacity to mate with another haploid gamete to create a diploid zygote. The fusion (or combining) of two gametes, namely a male and a female gamete, results in the zygote. Fertilization is the process through which two gametes combine to form a zygote.
One of the gametes is typically bigger and non-motile, which is characteristic. It is sometimes referred to as an ovum or an egg cell. The second gamete cell is smaller and motile. It is also known as a sperm cell or a male gamete. In humans, each gamete has 23 chromosomes, and when they fuse, a diploid zygote with 46 chromosomes is created. These reproductive cells are created in the gonads, or reproductive organs, of the male and female animals. The male gametes in seed-bearing plants are the pollen, whereas the female gametes are housed in the plant's ovules. The gamete in plants, however, is not invariably a haploid cell.
Hence, Uneven gamete division causes the chromosomal abnormalities.

A 2.00-kg object A is connected with a massless string across a massless, frictionless pulley to a 3.00-kg object B. Object A rests on a nearly frictionless plane, which is tilted at an angle of 40.0∘ as shown.
Answer:
tension: 19.3 Nacceleration: 3.36 m/s^2Explanation:
Given
mass A = 2.0 kg
mass B = 3.0 kg
θ = 40°
Find
The tension in the string
The acceleration of the masses
Solution
Mass A is being pulled down the inclined plane by a force due to gravity of ...
F = mg·sin(θ) = (2 kg)(9.8 m/s^2)(0.642788) = 12.5986 N
Mass B is being pulled downward by gravity with a force of ...
F = mg = (3 kg)(9.8 m/s^2) = 29.4 N
The tension in the string, T, is such that the net force on each mass results in the same acceleration:
F/m = a = F/m
(T -12.59806 N)/(2 kg) = (29.4 N -T) N/(3 kg)
T = (2(29.4) +3(12.5986))/5 = 19.3192 N
__
Then the acceleration of B is ...
a = F/m = (29.4 -19.3192) N/(3 kg) = 3.36027 m/s^2
The string tension is about 19.3 N; the acceleration of the masses is about 3.36 m/s^2.

The first stage of a space vehicle consumed fuel and oxidizer at the rate of 1.75 x 104 kg/s, with an exhaust speed of 2.40 x 103 m/s. Find the acceleration (in m/s2) of the vehicle just as it lifted off the launch pad on the Earth, if the vehicle's initial mass was 3.00 x 106 kg. (Note: You must include the force of gravity to solve the problem.)
Answer:
\(a=4.19 m/s^{2}\)
Explanation:
In order to solve this problem, we must first draw a free body diagram of the situation. (See attached picture)
from this diagram, we can do the following sum of forces:
\(\sum F=ma\)
where m is the mass of the rocket and a is its acceleration.
\(F_{e}-mg=ma\)
where \(F_{e}\) is the force of exhaust. We can solve this for the acceleration, so we get:
\(a=\frac{F_{e}-mg}{m}\)
we can find the force of exhaust by using the momentum formula:
Ft=mv
so we can solve this for the force:
\(F_{e}=\frac{mv}{t}\)
the problem already tells us what m/t is equal to, so we can directly substitute:
\(F_{e}=(1.75x10^{4}kg/s)(2.40x10^3m/s)\)
which yields:
\(F_{e}=42x10^6 N\)
So we can now substitute:
\(a=\frac{42x10^6N-(3x10^6kg)(9.81m/s^{2})}{3x10^6kg}\)
so:
\(a=4.19 m/s^{2}\)

Consider a satellite in a circular geostationary orbit about the Earth, meaning it orbits above a fixed point on the Earth's equator.
You may use the following values in your calculations:
- Mass of the Earth, M is 6.0x1024kg;
- Gravitational constant G, is 6.67 x 10-11 N m2 kg-2
- Radius of the Earth, r is 6400 km or 6.4 x 106 m. At what distance from the centre of the Earth does the satellite orbit?
Answer:
m V^2 / R = G M m / R^2 balancing forces
R = G M / V^2 (I)
V = 2 π R / (24 * 3600) to complete 1 rev in 24 hrs
V = π R / (12 * 3600) = R * 7.27E-5
V^2 = R^2 * 5.29E-9
R = G M / (R^2 * 5.29E-9) using (I)
R = (G M / 5.29E-9)^1/3
R = (6.67E-11 * 6.0E24 / 5.29E-9)^1/3
R = (66.7 * 6.0 / 5.29)^1/3 E7
R = 4.22E7 meters = 42200 km about 7 earth radii

The energy that something has because of its position--a book held 20 feet above the ground has more of this than a book held 5 feet off the ground.
The most common types of energy an object can have are:
- Kinetic energy: energy related to the movement. If an object has velocity, it has kinetic energy. The faster the object, higher is its kinetic energy.
- Potential energy: energy related to the height, to gravity. The higher (bigger height) an object is from a reference point, higher is its potential energy.
So the energy of a book held 20 feet above ground being higher than the energy of a book held 5 feet above ground, this energy is the potential energy.

a man carries a hand bag by hanging on his hand and moves horizontally where the bag does not move up or down. What is the work done on the bag? The man gets tired after sometime of the movement. Why
The work that the man does is the scalar product of the force applied by the man and the horizontal displacement of the bag.
What is the work done?In Physics, we define the work done as the product of the of force and distance. Hence, we generally define the work done as that which occurs when the force applied moves a distance in the direction of the force. This implies that the work done is not a vector but a scalar quantity.
In relation to the man and the bag, the work done is the product of the force that the man applies and the displacement of the bag. As such, the reason for the tiredness of the man is that the internal energy that he possesses is transferred to moving the bag.
Thus, the work that the man does is the scalar product of the force applied by the man and the horizontal displacement of the bag.

The magnitude of the power dissipated in resistor R4 is approximately 10,028 watts.
How to find magnitude?To find the power dissipated in resistor R4, use the formula:
P = I² × R
where P = power, I = current flowing through the resistor, and R = resistance of the resistor.
The total resistance, Rt, can be calculated using the formula:
1/Rt = 1/R1 + 1/R2 + 1/R3
Substituting the given values:
1/Rt = 1/3 + 1/0.8 + 1/2
Simplifying the equation:
1/Rt ≈ 1.6667
Rt ≈ 0.6 Ω
Next, calculate the total voltage, Vt, by summing the individual voltage sources:
Vt = ε1 + ε2 + ε3
Substituting the given values:
Vt = 9 + 6 + 4
Vt = 19 V
Now calculate the current flowing through resistor R4 using Ohm's Law:
I = Vt / Rt
Substituting the calculated values:
I = 19 / 0.6
I ≈ 31.6667 A
Finally, calculate the power dissipated in resistor R4:
P = I² × R4
Substituting the calculated values:
P = (31.6667)² × 10
P ≈ 10,028 W
Therefore, the magnitude of the power dissipated in resistor R4 is approximately 10,028 watts.

a) It is the error present in the measuring instrument that causes it to register a value even when there is no input or output being measured.
b) An example of when you would have to allow for zero error is when using a measuring instrument like a vernier caliper or micrometer screw gauge.
a) Zero error refers to the deviation or discrepancy in the measurement instrument, where the indication or reading on the instrument is not zero when the quantity being measured is zero. In other words, it is the error present in the measuring instrument that causes it to register a value even when there is no input or output being measured.
Zero error can occur due to various reasons such as manufacturing defects, wear and tear, misalignment, or improper calibration of the instrument. It can be positive or negative, depending on whether the instrument reads higher or lower than the actual value.
b) An example of when you would have to allow for zero error is when using a measuring instrument like a vernier caliper or micrometer screw gauge. These instruments are commonly used to measure the dimensions of objects with high precision.
In a vernier caliper, for instance, zero error can occur when the jaws do not close perfectly when there is no object being measured. If the caliper shows a reading other than zero when the jaws are closed, it indicates the presence of zero error.
To obtain accurate measurements, the zero error needs to be accounted for and compensated. This can be done by adjusting the position of the zero on the scale or by subtracting the zero error value from the measured readings.
