The markdown price for a mountain bike is $584.35

Markdown price is the discount offered by the shopkeepers to the customers to increase the sales rate.

M.P = S.P (1-r/100)

The following expression can be used every time we have to find the markdown price.

Substitute Selling price S.P =$899 and the percent r =35/100 =0.35, we get

M.P = $899(1-0.35)

M.P =$584.35

Thus, the markdown price is $584.35

Answer:

100N

Explanation:

Both rocks hit the ground at the same time and at the same distance from the base of the cliff. Option A is correct.

Speed is defined as the rate of change of the distance or the height attained. it is a time-based quantity. it is denoted by u for the initial speed while u for the final speed. its SI unit is m/sec.

If the  resistance is ignored, things falling near the Earth's surface have the same estimated acceleration due to gravity of 9.8 meters per second.

As a result, the objects' acceleration is the same, and their velocity is growing at a consistent pace.

So that both rocks hit the ground at the same time and at the same distance from the base of the cliff.

Hence, option A is correct.

The length the student should record as correct is ​18.55 centimeters (cm) because it is the average value.

The average value is a number associated with the middle amount for a given number of measured samples.

In this case, the median value results less useful to describe a set of data when compared to the average.

In conclusion, the length the student should record as correct is ​18.55 centimeters (cm) because it is the average value.

The motorcycle's average velocity will be 6 m/sec. The ratio of the overall distance traveled to the total time taken by the body is the average velocity.

The average velocity is the ratio of the total distance traveled to the total time taken by the body. Its unit is m/sec.

Total distance travelled by the  motorcycle;

d=20 m+10 m

d=30 m

The average velocity is found as;

[tex]\rm v_{avg}=\frac{d}{t} \\\\ \rm v_{avg}=\frac{30}{5} \\\\ v_{avg}= 6 \ m /sec[/tex]

Hence,the motorcycle’s average velocity will be 6 m/sec.

The quantity of heat that was transferred to the block of iron is 5544 J or 5.544 kJ

From the question, we are to determine how much heat was transferred to the block of iron

Using the formula,

Q = mcΔT

Where Q is the quantity of heat

m is the mass

c is the specific heat capacity of the substance

and ΔT is the change in temperature

From the given information,

m = 0.400 kg

ΔT = 325 - 295 = 30 K

Putting the parameters into the equation, we get

Q = 0.400 × 462 × 30

(NOTE: Specific heat capacity of iron = 462 J/kg.K)

∴ Q = 5544 J

Hence, the quantity of heat that was transferred to the block of iron is 5544 J or 5.544 kJ

1. The length of the bridge is 360 m.

2. The speed of train in km/hr to cross the bridge in 24 s is 72 km/hr.

3. The length of the train when it cross the bridge in 36 seconds is 540 m.

What is speed?

Speed is the ratio of distance traveled and the time taken to cover that distance.

1.

The speed of train m/s is 54 x 5/18 = 15 m/s

The train crosses the bridge in 32 s, distance traveled by train will be

=32 x 15 =480m

The length of the bridge = (480 -120) =360 m

Thus, the length of the bridge is 360 m.

2.

Speed of train in m/s to cross the bridge in 24 s

= 480/24 = 20 m/s

Speed in km/hr =20 x 18/5 = 72 km/hr

Thus, Speed of train in km/hr to cross the bridge in 24 s is 72 km/hr.

3.

Speed of train in m/s =15 m/s

Train crosses the bridge in 36 s, then length of train will be

= 15 x 36m = 540m

Thus,  the length of the train when it cross the bridge in 36 seconds is 540 m

Answer: 911.625

Explanation:

Answer:

Answer:

Mass of Earth (M1) = 6×10^24 kg

Mass of Puppy (M2) = 3.6 kg

Radius (R) = 6371000 m

Universal Gravitational Constant (G) = 6.67 × 10^11

Now,

Gravitational Force = G×M1×M2 / R^2

GF = 6.67 × 10^11 × 6 × 10^24 × 3.6 / (6371000)^2

GF = 144.072 × 10^35 / 40,589,641,000,000
