The Lewis structure of BrF3 comprises three Fluorine atoms surrounding a central Bromine atom (Br) (F).

Each fluorine atom and the bromine atom (Br) are connected by three single bonds (F). The Bromine atom (Br) has two lone pairs, whereas all three of the Fluorine atoms have three lone pairs (F). Since the bromine atom's two lone pairs lead the molecule to be twisted or distorted, BrF3 (bromine trifluoride) is a polar molecule in nature. Because of the uneven charge distribution between the three fluorine atoms and th bromine atom, the BrF3 molecule is polar. The compound BrF3 is sp3d hybridised from the BrF3 Lewis structure, and three fluorine atoms are bound to Br in a T-shape with two lone pairs.

The freezing temperature in Celsius is 0 degrees Celsius (°C).

Freezing temperature is the temperature at which a liquid transitions to a solid state. The value of the freezing temperature depends on the chemical composition of the liquid, as well as the surrounding pressure and other factors.

For pure water, the freezing temperature in Celsius is 0°C (32°F) at standard atmospheric pressure. This means that when the temperature of liquid water drops to 0°C, it will begin to freeze and solidify into ice. However, if other substances are added to the water, such as salt or sugar, the freezing temperature will be lowered due to the phenomenon of freezing point depression.

The car can travel approximately 316 miles on one gallon of gas, assuming that all of the energy released by the combustion of the gasoline is used to make the car go one mile.

Energy, 1.00 x 10^8 J flows directly into the surroundings in the form of heat. The amount of energy that can be used to make the car go one mile is:

E = 1.19 x 10^8 J - 1.00 x 10^8 J = 0.19 x 10^8 J

Work, W = F × d

where W is the work done, F is the force required to move the car, and d is the distance traveled.

6.0 x 10^5 J of work is required to make the car go one mile,

F = W/d = 6.0 x 10^5 J / 1609 m = 372.9 N

The requried load will have 400 Newtons of force applied to it, even though only 200 Newtons of effort force are used to lift it.

In a compound pulley, the load is lifted by multiple pulleys that are arranged in a certain way to increase the mechanical advantage. The mechanical advantage of a pulley system is determined by counting the number of strands of the rope that support the load.

Assuming an ideal, frictionless pulley system, the mechanical advantage of a compound pulley with two pulleys is 2. This means that the load is lifted with twice the force of the effort force.

So if 200 Newtons of effort force are applied to a compound pulley with a mechanical advantage of 2, the load will be lifted with a force of 2 x 200 Newtons, or 400 Newtons. Therefore, the load will have 400 Newtons of force applied to it, even though only 200 Newtons of effort force are used to lift it.

The absolute refractory period is a period of time after a neuron fires an action potential during which it is unable to fire another action potential, no matter how strong the incoming stimulus be.

This is caused by the opening and closing of ion channels in the neuron's cell membrane. During an action potential, the neuron's membrane potential rapidly depolarizes, meaning it becomes more positive, due to the influx of positively charged ions such as sodium. This depolarization activates voltage-gated ion channels that allow more positively charged ions to flow into the cell, which in turn causes the membrane potential to further depolarize.

However, during this depolarization phase, there is a brief period where voltage-gated potassium channels also open, allowing positively charged potassium ions to flow out of the cell. This outflow of positively charged potassium ions helps to repolarize the membrane potential, bringing it back towards its resting state.

After the potassium channels close, there is a brief period during which the membrane potential is hyperpolarized, meaning it becomes even more negative than its resting state. During this time, the neuron is in its absolute refractory period and is unable to fire another action potential, because the voltage-gated ion channels are closed and unable to respond to incoming stimuli.

For a pair of objects, the center of mass is located option (D) along the line between the two objects, closer to the more massive object.

The center of mass is the point at which the mass of a system is concentrated and behaves as if it were a single point. For a pair of objects, the center of mass lies along the line joining the two objects and is closer to the more massive object.

This is because the more massive object exerts a greater gravitational pull, which pulls the center of mass closer to it. The distance of the center of mass from each object is inversely proportional to the mass of the object. Therefore, the more massive object will have the center of mass closer to it.

Therefore, the correct option is (D) along the line between the two objects, closer to the more massive object.

The specific gravity of water at exactly 4°C is 1 and the density of water depends on the temperature of water.

A substance's specific gravity is determined by dividing its material's density by that of a standard liquid. The reference liquid is generally water. As a result, the specific gravity can also be explained as the relation of the material's density to water's density.

A common tool for determining a liquid's specific gravity is the hydrometer. A hydrometer is a floating bulb with measurement markers affixed to a stalk. The relative density of the two liquids can be calculated by measuring how much of the stalk is immersed in the target liquid in comparison to a reference liquid.

Another tool for determining a liquid's density while accounting for volume is a pycnometer. The container is made of glass, and the tight-fitting lid lets any extra liquid out.

The number of seconds in 365 days is 31,536,000 seconds.

The number of days in a year is 365 days. The number of hours in a day is 24 hours. The number of minutes in an hour is 60 minutes. The number of seconds in a minute is 60 seconds. So the number of seconds in a year is 365×24×60×60 = 31536000 seconds.

There are 31,536,000 seconds in a year. This is calculated by multiplying the number of seconds in a minute (60) by the number of minutes in an hour (60) by the number of hours in a day (24) by the number of days in a year (365).

However, it's worth noting that a year is not always exactly equal to 31,536,000 seconds. Because the length of a year is not exactly equal to 365 days, a leap year has an additional day (366 days).

Speed in physics refers to how fast an object is moving. It is a scalar quantity that only takes into account the magnitude of the velocity of the object, not its direction. The speed of an object can be calculated by dividing the distance it travels by the time it takes to travel that distance. The SI unit of speed is meters per second (m/s), but other units such as miles per hour (mph) or kilometers per hour (km/h) can also be used.

Speed can be constant, meaning the object is moving at a steady rate, or it can be changing, meaning the object is accelerating or decelerating. Acceleration is the rate at which an object's speed changes over time, and it is typically measured in meters per second squared (m/s^2).
