A polar covalent bond is one where electrons are unequally shared between the atoms in the bond. option (c)

In a covalent bond, atoms share electrons to form a stable compound. However, in some cases, the electrons are not shared equally between the atoms, resulting in a partial positive charge on one atom and a partial negative charge on the other. This unequal sharing of electrons occurs when one atom has a higher electronegativity (ability to attract electrons) than the other. The atom with higher electronegativity attracts the electrons closer to itself, resulting in a partial negative charge on that atom, while the other atom has a partial positive charge. For example, in the water molecule (H2O), the oxygen atom is more electronegative than the hydrogen atoms. As a result, the electrons in the covalent bond are pulled closer to the oxygen atom, giving it a partial negative charge, while the hydrogen atoms have a partial positive charge.

Polar covalent bonds play an essential role in many biological processes, such as the formation of DNA and proteins, and are crucial in understanding the properties of many chemical compounds. option (c)

The bullet fired at an angle of 80° with the horizontal and an initial velocity of 420 m/s can travel up to a height of 825.4 meters and a horizontal distance of 80.1 meters after 2 seconds.

To determine the height and horizontal distance traveled by a bullet fired at an angle of 80° with the horizontal and an initial velocity of 420 m/s after 2 seconds, we can use the equations of motion.

Firstly, we can break down the initial velocity of the bullet into its horizontal and vertical components. The horizontal component remains constant throughout the motion and is given by:

Vx = Vcosθ

where V is the initial velocity and θ is the angle of projection. Substituting the given values, we get:

Vx = 420cos80° = 40.05 m/s (approx.)

The vertical component of the initial velocity can be calculated as:

Vy = Vsinθ

Substituting the given values, we get:

Vy = 420sin80° = 416.95 m/s (approx.)

Now, we can use the following equations of motion to determine the height and horizontal distance traveled by the bullet after 2 seconds:

Vertical motion:

y = yo + Voyt + (1/2)gt^2

where y is the vertical displacement, yo is the initial height (assumed to be zero), Voy is the initial vertical velocity, g is the acceleration due to gravity (9.8 m/s^2), and t is the time.

Substituting the given values, we get:

y = 0 + 416.95(2) - (1/2)(9.8)(2)^2

y = 825.4 m (approx.) Therefore, the bullet can travel up to a height of 825.4 meters after 2 seconds. Horizontal motion:

x = xo + Voxt

where x is the horizontal displacement, xo is the initial horizontal position (assumed to be zero), Vox is the initial horizontal velocity, and t is the time.

Substituting the given values, we get:

x = 0 + 40.05(2)

x = 80.1 m (approx.)

Therefore, the bullet can travel a horizontal distance of 80.1 meters after 2 seconds.

In summary, the bullet fired at an angle of 80° with the horizontal and an initial velocity of 420 m/s can travel up to a height of 825.4 meters and a horizontal distance of 80.1 meters after 2 seconds.

The coefficient of friction between the two blocks is 0.194.

The problem involves finding the coefficient of friction between two blocks of equal mass attached by a string that moves over a sloped ramp with an angle of 30 degrees. The blocks start from rest and are allowed to move freely. The distance traveled by the blocks is 0.50 m, and the time taken to travel this distance is 0.935 s. To solve the problem, we need to consider the forces acting on the system of blocks. The forces acting on the blocks are the gravitational force, the tension in the string, and the frictional force. As the blocks are moving up the ramp, the force of gravity is pulling them down. The tension in the string is pulling the blocks up the ramp. The frictional force is opposing the motion of the blocks and is acting in the opposite direction to the tension in the string.

To determine the coefficient of friction, we can use the equations of motion to find the acceleration of the blocks. Once we have the acceleration, we can use Newton's Second Law to find the net force acting on the blocks. We can then use the force of friction to find the coefficient of friction. Using the equations of motion, we can find the acceleration of the blocks:

a = 2d/t^2

where d is the distance traveled by the blocks and t is the time taken to travel the distance. Plugging in the given values, we get:

a = 2(0.50 m)/(0.935 s)^2 = 1.15 m/s^2

Next, we can use Newton's Second Law to find the net force acting on the blocks:

ΣF = ma

where ΣF is the sum of the forces acting on the blocks. Plugging in the known forces, we get:

T - mg sin θ - μmg cos θ = ma

where T is the tension in the string, m is the mass of the blocks, g is the acceleration due to gravity, θ is the angle of the ramp, and μ is the coefficient of friction.

We can simplify this equation by substituting mg sin θ for the component of the weight of the blocks that is acting down the ramp and mg cos θ for the component of the weight that is acting perpendicular to the ramp:

T - mg sin θ - μmg cos θ = ma

T - mg(1/2) - μmg(√3/2) = ma

We can also use the equation for the tension in the string:

T = 2mg sin θ

Substituting this into the equation for net force, we get:

2mg sin θ - mg(1/2) - μmg(√3/2) = ma

Simplifying and solving for μ, we get:

μ = (2gsinθ - a)/(2gcosθ)

Substituting the given values, we get:

μ = (2(9.81 m/s^2)sin 30° - 1.15 m/s^2)/(2(9.81 m/s^2)cos 30°) = 0.194

Therefore, the coefficient of friction between the two blocks is 0.194.

From the given,

mass of ice (m) = 1kg = 1000g

Specific heat of ice (Ci) = 0.5 cal/gm.C

Specific heat of water(Cw) = 1 cal/gm.C

Latent heat of ice (Li) = 80 cal/gm

Latent heat of steam (Ls) = 540 cal/gm

The heat required to take the ice from -2°C to 0°C

Q = mCΔT = 1000×0.5×2 = 1000J

The heat required to melt ice at 0°C to water

Q = mL(i)ΔT = 1000×80 = 80,000J

The heat required to take 1kg of water from 0°C to 100°C

Answer:

A = 21 î + 28 ĵ

B = 12 î + 5 ĵ

Explanation:

a.

To write A and B in terms of î and ĵ, we need to use the trigonometric ratios and the vector notation

According to the diagram, we have:

tan a = 4/3 tan ß = 5/12

Using the identity tan θ = opposite/adjacent, we can find the x and y components of A and B.

For A, we have:

x component = 35 cos a y component = 35 sin a

Using tan a = 4/3, we can find cos a and sin a by using Pythagoras’ theorem:

cos a = 3/5 sin a = 4/5

Therefore, the x and y components of A are:

x component = 35 cos a = 35 (3/5) = 21 y component = 35 sin a = 35 (4/5) = 28

Using the vector notation, we can write A as:

A = 21 î + 28 ĵ

Similarly, for B, we have:

x component = 13 cos ß y component = 13 sin ß

Using tan ß = 5/12, we can find cos ß and sin ß by using Pythagoras’ theorem:

cos ß = 12/13 sin ß = 5/13

Therefore, the x and y components of B are:

x component = 13 cos ß = 13 (12/13) = 12 y component = 13 sin ß = 13 (5/13) = 5

Using the vector notation, we can write B as:

B = 12 î + 5 ĵ

b.

To show that A + B makes an angle of 45° to the x-axis, we need to find the resultant vector R and its angle θ with the x-axis.

To find R, we can use the vector addition rule :

R = A + B R = (21 î + 28 ĵ) + (12 î + 5 ĵ) R = (21 + 12) î + (28 + 5) ĵ R = 33 î + 33 ĵ

To find θ, we can use the inverse tangent function :

tan θ = y component / x component tan θ = 33 / 33 tan θ = 1

θ = tan^-1(1) θ = 45°

Therefore, A + B makes an angle of 45° to the x-axis.
