The average speed of the complete round trip is 65.57 km / h.

We need to know about the average speed to solve this problem. The average speed can be determined as the total distance divided by the total time. It can be written as

v = d / t

where v is average speed, d is distance and t is time.

From the question above, we know that

d1 = 300 km

v1 = 93 km/h

t lunch = 1 hour

d2 = 300 km

v2 = 56 km/h

Find the time during the outgoing

v1 = d1 / t1

t1 = d1 / v1

t1 = 300 / 93

t1 = 3.23 hours

Find the return time

v2 = d2 / t2

t2 = d2 / v2

t2 = 300 / 56

t2 = 5.36 hours

Hence, the total time

t = t1 + t2 + t lunch

t = 3.23 + 5.36 + 1

t = 9.59 hours

Find the average speed

v = d / t

v = (300 + 300) / 9.59

According to Transformation ratio,

[tex]V_{p}[/tex] / [tex]V_{s}[/tex] = [tex]I_{s}[/tex] / [tex]I_{p}[/tex]

where,

[tex]V_{p}[/tex] = Voltage across the primary coil

[tex]V_{s}[/tex] = Voltage across the secondary coil

[tex]I_{s}[/tex] = Current in the primary coil

The deceleration of the rocket sled if it comes to rest in 1.1 s from a speed of 1000 km/h is  [tex]252.52\ m/s^2[/tex].

The acceleration in opposite direction is known as the deceleration. Basically the deceleration is negative value of the acceleration since the negative sign depicts its opposite in direction.

The given data:

time, t = 1.1 s

initial speed, u = 1000 km/h = [tex]\frac{2500}{9}\ m/s[/tex]

final speed, v = 0 m/s

So we will be using the equation of motion, that is,

v = u + at

[tex]\therefore 0=\frac{2500}{9} + a(1.1)[/tex]

[tex]\Rightarrow a=-\frac{2500}{9(1.1)}[/tex]

Digital camera demand is inelastic if the price elasticity of demand is 0.88, meaning that price rises for cameras will result in higher overall sales.

Price elasticity of demand measures how much a product's consumption changes in response to price changes. If a good's price elasticity is infinite, it is perfectly elastic (if demand changes substantially even with minimal price change). The good is elastic if price elasticity is more than 1, and inelastic if it is less than 1. A good is completely inelastic if its price elasticity is zero, meaning that no amount of price variation will alter demand. The quantity effect will be overpowered by the price effect. The relationship between the percentage change in a product's quantity demanded and the percentage change in price is known as price elasticity of demand.

where P is pressure, V is volume, n is the amount of substance, R is the ideal gas constant (8.31 J/mol.K) and T is temperature.

From the question above, we know that:

Mr = 2 g/mol

ρ = 1.4 g/cm³

P = 1.3 x 10⁹ atm = 1.32 x 10¹⁴ Pa

m(sun) = 1989 x 10³⁰ g

Find the amount of sun substance

n = m / Mr

n = 1989 x 10³⁰ / 2

n = 994.5 x 10³⁰ mol

The seal's average velocity during the chase is 1.67 m/s.

The seal's average speed during the chase is 5 m/s.

The average velocity of an object is the change in the displacement of the object with time.

The seal's average velocity during the chase is calculated as follows;

Δx = xf - xi

Δx = 20 m - 10 m = 10 m

v = Δx/t

v = 10 m / 6 s

v = 1.67 m/s

The average speed is the ratio of total distance to total time of motion.

v = (10 m + 20 m) / 6 s

v = 30 m / 6s
