Ravi, Rajiv and Shyam are sitting inside a room. The body temperature of. Ravi, Rajiv and Shyam are 35.8 ℃, 36.2 ℃ and 36.4 ℃. It is given that the temperature of air present in the room is 36.1 ℃. Who among them will feel cold? Give Reason, please reply as soon as possible!! (explanation needed).

Answers

Answer:

"Cold" in this case, is defined as a difference between the body temperature and the room/ambient temperature.

If the body temperature is higher than the room temperature, then the "sensors" in our skin will sense that the ambient temperature is lower than ours, then we feel "cold"

The room temperature is: 36.1°C.

The higher body temperature is the one of Shyam, 36.4°C

The difference is really small:

36.4°C - 36.1°C = 0.3°C

But still, he will feel the room a little cold for him

The area of a triangle is 30 m². Using the equation A=12bh A = 1 2 b h , where b is base and h is height, solve for h if b = 3 m. Round to three decimal places, if necessary.

Answers

Answer:

20 metres

Explanation:

Given that the area of a triangle is 30 square metres (m²). Using the equation A = 1/2bh, this is the formula for the triangle.

where b is base and h is height

Given that b = 3 metres.

To calculate h, Substitute b and A into the equation

30 = 1/2 × 3 × h

3h = 60

h = 60/3

h = 20 m

Therefore, h is equal to 20 metres

Jan ran 4 miles north in 28 minutes. What was Jan's average velocity?

Answers

Answer:

3.83 m/s

Explanation:

Given that,

Distance covered by Jan, d = 4 miles

1 mile = 1609.34 m

4 miles = 6437.38 m

Time, t = 28 minutes = 1680 s

Jan's average speed,

v = d/t

[tex]v=\dfrac{6437.38\ \text{m}}{1680\ \text{s}}\\\\v=3.83\ \text{m/s}[/tex]

Hence, the average velocity of Jan is 3.83 m/s.

differences between a pair of scissors and nailcutter​

Answers

Answer:

Different classes of levers

Explanation:

The main difference between a pair of scissors and nailcutters is that they are different classes of levers. Scissors are made from two class 1 levers, meaning that the effort is exerted at one end and the load at the other with the fulcrum in the middle. This is because we press one end together (the handles) so we are applying the effort, and the other side closes from the fulcrum in the middle.

Nailcutters on the other hand, consist of two class 2 levers. This means that the fulcrum is on the opposite end to the effort with the load in the middle. This is because we press down on one side and the two parts move closer together.

A car travels 200 miles in 8 hours calculate the cars speed

Answers

Answer:

25 mi/hr

Explanation:

Distance = 200 miles

Time = 8 hours

[tex]Speed = \frac{Distance}{Time}[/tex]

Substitute values into the given equation and solve.

[tex]Speed = \frac{200}{8} \\\\Speed = 25 \:miles/hour[/tex]

A car travels 200 miles in 8 hours is 25 miles/h (25 mph).

What is Speed?

The speed of an object is defined as the magnitude of change of its position with time or the magnitude of change of its position per unit time. It is a scalar quantity which has only magnitude , no direction.

It can be expressed as:

[tex]s = \frac{d}{t}[/tex]

s = speed

d = distance traveled

t = time elapsed

The SI unit of speed is metre per second. (m/s)

For above given information,

Distance = 200 miles

Time= 8 hours

So, speed will be 200 miles/ 8 hrs

Speed = 25 miles/hr or 25 mph.

Thus , a car travels 200 miles in 8 hours is 25 miles/h (25 mph).

When it is 21 m above the ground, a package is released from the balloon. For
how long is it in the air?

Answers

Answer:

The time spent in air by the package is 1.5 s

Explanation:

Given;

speed of the balloon, v = 7.0 m/s

distance traveled by the balloon, d = 21 m

The time spent by the object in the air is give by;

d = vt + ¹/₂gt²

21 = 7t + ¹/₂(9.8)(t²)

21 = 7t + 4.9t²

4.9t² + 7t -21 = 0

solve this quadratic expression, and the value of t will be

t = 1.5 s

Therefore, the time spent in air by the package is 1.5 s

Percy threw a penny straight down off the Empire State building. The building is 354 m tall. If he threw the penny down such that it left his hand at 35 m/s, what is the acceleration of the penny? What will the velocity of the coin that Percy threw be when it hits the pavement?

Answers

Answer:

90.4 m/s

Explanation:

Take down to be positive.  For objects in free fall, the acceleration is 9.8 m/s².

Given:

Δy = 354 m

v₀ = 35 m/s

a = 9.8 m/s²

Find:

v² = v₀² + 2aΔy

v² = (35 m/s)² + 2 (9.8 m/s²) (354 m)

v = 90.4 m/s

You can easily get rid of A and B because they don’t tell you a lot about your plant on their own. As for C you could use a graph but they’re only good at giving you two forms of data, which are usually dependent data and time and you need three forms of data. Finally a table can hold as many different data points as you need and because you need three it would be wise to use a table not a graph.

Which property of an object is the result of gravity?
O A. Weight
B. Mass
O C. Velocity
OD. Volume

Answers

Answer:

it's (A) weight I think

Answer:

A. Weight

Explanation: Weight is defined as the amount of force placed on an object from gravity which means it is directly reliant on the force of gravity while the other choices are not. Neither Mass, volume, or velocity is impacted by gravity as much as weight, velocity is the direction of speed, mass is the resistance that a body of matter offers to a change in its speed or position upon the application of a force, and volume is the amount of space an object takes. As you can see none of these componant have gravity as a determining factor other than weight since weight is determined by the gravity which is why the weight of an object can vary if your on earth or on the moon since the gravity is different.

There are 100 simple pendulums in a room having identical bobs which are displaced to different extents but only 25 of these pendulums have different time periods. What do you think would be the reason?

Answers

Explanation:

The time period of a simple pendulum is given by :

[tex]T=2\pi \sqrt{\dfrac{L}{g}}[/tex]

L is length of the pendulum and g is acceleration due to gravity

It is very much clear that the time period depends on the length of the pendulum.

In this problem, there are 100 simple pendulums in a room having identical bobs which are displaced to different extents but only 25 of these pendulums have different time periods. The only reason for 25 pendulums having different time periods is that they have different lengths than the other 75 pendulums.

In many locations, old abandoned stone quarries have become filled with water once excavating has been completed. While standing on a 10.0 m high quarry wall, Clarence tosses a piece of granite into the water below. If Clarence throws the rock horizontally with a velocity of 3.0 m/s how far out from the edge of the cliff will it hit the water?

Answers

Answer:

Explanation:

Let us calculate the time of flight first using the formula;

Velocity = Displacement/Time

Time = Displacement/speed

Time = 10.0/3

Time = 3.33secs

Next is to calculate how far out from the edge of the cliff it will hit the water. To get that, we will use the equation of motion;

S= ut+1/2gt²

u is the initial velocity = 0m/s

g is the acceleration due to gravity = 9.81m/s

S = 0 + 1/2(9.81)(3.33)²

S = 4.905*3.33*3.33

S = 54.39m

Hence it will hit the water at 54.39m from the edge of the cliff

Answer:

It will hit the water at [tex]4.28m[/tex] off the cliff

Explanation:

Applying kinematic relations along vertical direction

[tex]y = V_0t + \frac{1}{2}a_yt^2[/tex]

where,

[tex]a_y = g[/tex]

therefore,

[tex]y = 0 + \frac{1}{2}gt^2[/tex]

The time taken

[tex]t = \sqrt{\frac{2y}{g}}\\\\t = \sqrt{\frac{2*10}{9.8}}\\\\t = 1.428s[/tex]

The horizontal distance

[tex]x = V_yt\\\\x = 3*1.428\\\\x = 4.28m\\\\[/tex]

Answers

Answer:

Average speed = 40.50 km/h (Approx)

Total distance = (40/60) 50 + (8/60) 70 + (35/60) 35

Total distance = 33.33 km + 9.33 km + 20.17 km

Total distance = 62.80 km

Average speed = Total distance / Total time taken

Average speed = 62.80 / [(40+8+35+40)/60]

Average speed = 62.80 / 1.55

Answers

Answer:

W = 222 N.

Explanation:

The qiestion says" If the acceleration of gravity on the surface of the planet Mercury is 3.7 m / s2, then what would be the weight of a person with mass 60 kg on its surface? "

Mass of the person, m = 60 kg

The acceleration due to gravity on the surface of gravity is 3.7 m/s²

We need to find the weight of a person on the surface of Mercury.

Weight of an object is given by :
