During which season at what latitude does the sun not set

Answers

Answer 1

Answer:

Answer:

In summer season, sun would not set at latitude 66.5 N and above. In summer season for southern hemisphere, sun would not set for latitude 66.5 S and above.

Explanation:

Season on Earth occurs due to the inclination of the axis about which it rotates. Due to this, there is different length of day and night in different hemispheres at a time.

Sun is highest in the sky in northern hemisphere in summers. So the places at 66.5 N and higher latitude experience 24 hours sun light.

Similarly, in northern hemisphere summers, places at 66.5 S and higher latitude experience 24 hours sun light.

Answer 2

Answer:

The sun not set in the summer and greater than 66 N

I hope that's help !

Newton discovered that gravity behaves differently in space than it does on Earth. true or false?

Answers

Yes. It is true. Gravity behaves differently than on earth. In-fact, as we go above the earth surface the gravity decreases. Gravity as we go above the earth surface can be calculated using following formula:

g' = g(1-2h/R)

Hence, it is true that the gravity behaves differently than on earth.

Which of the following are adaptions of the digestive system in land-dwelling herbivores?A. Flat teeth and longer intestinal tracts
B. More fat cells to store energy
C. Strong jaws and sharper teeth
D. Removal of ammonia through gills

Answers

Answer: A

Land dwelling herbivores have flatter teeth, to help with chewing plants (as opposed to canines to rip through flesh). They also have a longer intestinal track, this is because plants don't putrefy in the body as quickly as raw meat will, so a longer intestinal track doesn't hurt herbivores.

Explanation:

you are moving fast on a skateboard when your wheel gets stuck in a crack on the sidewalk using the term inertia explain what happens

Answers

Answer:

Inertia is the tendency or ability of a body to remain at rest or in uniform motion along a straight line in the absence of any external force. It is the reluctance a body displays when agitated or encountered by an external.

By the law of inertia, an object will always remain in its position of rest or state of uniform motion along a straight line until it is engaged with an external force.

To put it in other words;

When an object is at rest, it will want to remain at rest. If it becomes engaged with an external force it will display some reluctance before it changes its mechanical state.

Similarly, when an object is in uniform motion, it will want to continue with the motion. If an external force then interrupts it, it will also display some reluctance. This reluctance is in the form of it wanting to continue its motion irrespective of the force.

So therefore if I am moving fast on a skateboard and suddenly I become interrupted with a force, by the law of inertia my tendency is to continue the motion and this makes me exhibit reluctance in responding to the force. This reluctance will then make me to topple over and fall off if there is nothing to quickly hold unto. The more massive I am, the greater the effect of the topple. The inertia of an object is proportional to its mass.

When the wheels of the skateboard get stuck in the crack of the sidewalk, the riders inertia will continue forward and cause him to fall off/down.

True or false: distance traveled and displacement can be equal.

Answers

Answer:

true

Explanation:

Answer:

When the object is moving in a straight line distance will be equal to displacement. ... Shortest path = Actual path,because object travelled in a straight line. Displacement and Distance should have same magnitude because the object has not changed its direction.

Explanation:

With a slope of 6.4%A car starts at 0mph, and has a top speed of 203
And has a base acceleration of 2.93ft/s2
How long would it take to reach 12.42 miles

Answers

Answer: 271.4 s

Explanation:

We are told the top speed (maximum speed) $V_(max)$ the car has is:

$V_(max)=203 mph=90.74 m/s$ taking into account $1 mile=1609.34 m$

And the car's base acceleration (average acceleration) $a_(ave)$ is:

$a_(ave)=2.93 ft/s^(2)=0.89 m/s^(2)$

Since:

$a_(ave)=(V_(f)-V_(o))/(\Delta t)$ (1)

Where:

$V_(f)=V_(max)=90.74 m/s$ is the car's final speed (top speed)

$V_(o)=0 m/s$ because it starts from rest

$\Delta t$ is the time it takes to reach the top speed

Finding this time:

$\Delta t=(V_(f)-V_(o))/(a_(ave))$ (2)

$\Delta t=(90.74 m/s - 0 m/s)/(0.89 m/s^(2))$ (3)

$\Delta t=t_(1)=101.95 s$ (4)

Now we have to find the distance $d$ the car traveled at this maximum speed with the following equation:

$V_(f)^(2)=V_(o)^(2) + 2a_(ave) d$ (5)

Isolating $d$ :

$d=(V_(f)^(2))/(2a_(ave))$ (6)

$d=((90.74 m/s)^(2))/(2(0.89 m/s^(2)))$ (7)

$d=4625.70 m$ (8)

On the other hand, we know the total distance $D$ traveled by the car is:

$D=12.42 miles = 19988.052 m$

Hence the remaining distance is:

$d_(remain)=D-d=19988.052 m - 4625.70 m$ (9)

$d_(remain)=15362.35 m$ (10)

So, we can calculate the time $t_(2)$ it took to this car to travel this remaining distance $d_(remain)$ at its top speed $V_(max)$ , with the following equation:
