An airplane flying directly toward it from the east is spotted by a radar station. The distance to the plane at initial observation is 385.0 m at 41.0 °. 302.26m is the displacement.
What is displacement?Displacement is defined as a shift in an object's position. It is a vector quantity with direction and magnitude. An arrow pointing from the starting location to the finishing position is used to represent it. For instance, if an object moves from position A to position B, its position changes. The term used to describe this change in an object's position is displacement.
The instantaneous velocity of the item is the rate at which the displacement changes as a function of time when studying the motions of objects across time. Therefore, the instantaneous speed is different from the velocity, or the rate at which the distance traveled along a particular path changes over time. The temporal rate of change can also be used to define the velocity. The velocity of P (for example, a point representing the position of a passenger walking on the train) may be referred to as a relative velocity as opposed to an absolute velocity, which is computed with respect to a point which is considered to be "fixed in the space," if one takes into consideration a moving initial position or, equivalently, a moving origin (e.g., an initial position or the origin which is fixed to a train wagon, which in turn moves on its rail track) (such as, for instance, a point fixed on the floor of the train station).
Therefore,

a cannon is fired from the ground at an angle of 27.0° from the horizontal with an initial velocity of 56.0 m/s.
The cannon in projectile motion has a maximum range of: 258.88 m, and a maximum height of: 32.096 m
The formulas for projectile motion that we will use to solve this exercise are:
x max = (vi² * sin 2*θ) /g h max = [vi² * (sinθ)²] / (2*g)Where:
h max = maximum heightx max = maximum rangeg = gravityvi = initial velocityInformation about the problem:
vi = 56.0 m/sθ= 27.0ºg = 9.8 m/s².x max = ?h max = ?Applying the maximum range formula we get:
x max = (vi² * sen 2*θ) /g
x max = {(56.0 m/s)² * (sen 2*27.0)} / 9.8 m/s²
x max = 258.88 m
Applying the maximum height formula we have:
h max = (vi² * (senθ)²) / (2*g)
h max = [(56.0 m/s)² * (sin 27.0º)²] / (2 * 9.8 m/s²)
h max = 32.096 m

5. (a) Calculate Earth's average speed relative to the Sun. (b) What is its average velocity over a period of one year?
a. The Earth's average speed relative to the Sun is 2970 m/s
b. The earth's average velocity over a period of one year is 0 m/s
(a) Calculate Earth's average speed relative to the Sun.The speed of the earth relative to the sun is given by v = √(GM/r) where
G = universal gravitational constant = 6.67 × 10⁻¹¹ Nm²/kg², M = mass of sun = 1.989 × 10³⁰ kg and r = distance of earth from sun = 1.5043 × 10¹¹ mSubstituting the values of the variables into the equation, we have
v = √(GM/r)
v = √(6.67 × 10⁻¹¹ Nm²/kg² × 1.989 × 10³⁰ kg/1.5043 × 10¹¹ m)
v = √(13.26663 × 10¹⁹ Nm²/kg/1.5043 × 10¹¹ m)
v = √(8.8191 × 10⁸ Nm²/kg)
v = 2.97 × 10⁴ m/s
v = 2970 m/s
So, the Earth's average speed relative to the Sun is 2970 m/s
(b) What is its average velocity over a period of one year?The average velocity of the Earth is v = ΔD/T where
ΔD = total dispalcement = D' - D where D = initial position of earth and D' = final position of earth and T = period of earth over one year = 365 days × 24 h/day × 60 min/h × 60 s/min = 31536000 s = 3.1536 × 10⁸ sNow, since the earth starts and stopps at the same position, D' = D.
So, ΔD = D' - D = 0
Substituting the values of the variables into the equation, we have
v = ΔD/T
v = 0 m/3.1536 × 10⁸ s
v = 0 m/s
So, the earth's average velocity over a period of one year is 0 m/s

How much additional time will pass before the ball passes the tree branch on the way back down?
The additional time pass before the ball passes the tree branch on the way back down is 1.913 .
Consider the displacement equation
s(t) = (-g/2)t^2 + v(0)t + s(0)
where g = 9.8 m/s/s is the acceleration due to gravity,
v(0) = 15 m/s is the initial velocity, and
s(0) = 0 is the staring position (the ground).
We want to know when s(t) = 7 m. Thus,
7 = (-9.8/2)t^2 + 15t
We solve for t by solving the quadratic
(-9.8/2)t^2 + 15t - 7 = 0
Using the Quadratic Formula, we get the two roots
t1 = .574 seconds
t2 = 2.487 seconds
These two values represent the times when the ball passes the tree branch. Therefore, the total time between passing the branch is the difference between 2.49 seconds and 0.57 seconds.

Answer:
The forward voltage is decreased by 17.31 MV if an identical diode is connected in parallel and the junction diode is operated in a circuit in which it is supplied with a constant current.
Explanation:
There are two instances to consider in this question;
Instance 1: when a single diode is supplied with a constant current II as shown below in (a). We assume that I1 = I which generates a forward voltage V1 across this diode.
Instance 2: when an identical diode is connected in parallel with the previous diode as shown below in (b). In this case the current flowing through each of them is I2 = I/2 and this current generates a forward voltage V2 across each of the two diodes.
V2 - V1 = 2.303 Vt log (I2/I1)
V2 = V1 + 2.303 Vt log (I2/I1)
V2 = V1 + 2.303 * 25 MV * log (I/2/I)
V2 = V1 + 2.303 *25 MV * log (1/2)

c = circumference of a sphereπ = mathematical constantr = radiusv= volume d= densitym= massInformation about the problem:
c = 23500 kmd = 2.41 g/mlπ = 3.14161 metric tone = 1000 kgr=?v = ?m =?Applying the circumference of a sphere formula and clearing the radius we get:
c = 2 * π * r
r = 23500 km / 2 * 3.1416
r = 3740.132 km
Applying the volume of the sphere formula we get:
v= (4 *π * r³) / 3
v= (4 *3.1416 * (3740.132 km)³) / 3
v = 2,1915 *10^11 km³

m = d * v
m = 2.41 g/ml * 2.1915*10^16 ml
m = 5.2815*10^16 g
By converting the mass units from (g) to (metric tone) we have:

For adding to vectors, we add the x and y components separately, and then find the resultant vector =
Resultant x component + resultant y component
Adding the X component,
5x+4x=9x
Adding the Y component,
2y+6y=8y
Therefore, the resultant vector is 9x+8y.
What is a resultant vector?The vector sum of vector addition is just the consequence. It is the result of multiplying at least two vectors together. The outcome of adding the displacement vectors A, B, and C is vector R. An appropriately drawn, scaled, vector addition diagram can be used to compute vector R, as illustrated in the diagram.

Human hox genes are in four clusters: HOXA, HOXB, HOXC, and HOXD for a total of 39 genes. besides conserving the clustering of genes, evolution has also conserved the order of genes within them.
What is a gene?
A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes helps to make molecules called proteins. However, many genes do not synthesis for proteins. Every person has two copies of each gene, one inherited from each parent. Most genes are the same in all people, but a small number of genes (less than 1 percent of the total) are slightly different among the people. Alleles are forms of the same gene with small differences in their sequence of DNA bases. These small differences contribute to each person’s unique physical features.
