Answer:

23.67 km / hr

Explanation:

car travels 355 km (d)

duration = 15 hrs  (t)

average speed formula = v = d / t

v = 355 km / 15 hr

v = 23.67 km / hr

Explanation:

<em>Hello</em><em>,</em><em> </em><em>there</em><em>!</em><em>!</em><em>!</em>

<em>Here</em><em>,</em><em> </em><em>your</em><em> </em><em>question</em><em> </em><em>is</em><em> </em><em>asking</em><em> </em><em>about</em><em> </em><em>the</em><em> </em><em>speed</em><em> </em><em>and</em><em> </em><em>the</em><em> </em><em>given</em><em> </em><em>are</em><em>:</em>

<em>distance</em><em> </em><em>(</em><em>s</em><em>)</em><em>=</em><em> </em><em>3</em><em>5</em><em>5</em><em>km</em>

<em>time</em><em> </em><em>(</em><em>t</em><em>)</em><em> </em><em>=</em><em> </em><em>1</em><em>5</em><em>hrs</em><em>.</em>

<em>speed</em><em> </em><em>(</em><em>v</em><em>)</em><em>=</em><em>?</em>

<em>now</em><em>,</em><em> </em>

<em>we</em><em> </em><em>have</em><em> </em><em>the</em><em> </em><em>formula</em><em>:</em>

<em> </em>

<em>v</em><em>=</em><em> </em><em>s</em><em>/</em><em>t</em>

<em>or</em><em>,</em><em> </em><em>v</em><em> </em><em>=</em><em> </em><em>3</em><em>3</em><em>5</em><em>km</em><em> </em><em>/</em><em>1</em><em>5</em><em> </em><em>hrs</em><em>.</em>

<em>Therefore</em><em>,</em><em> </em><em>the</em><em> </em><em>speed</em><em> </em><em>of</em><em> </em><em>car</em><em> </em><em>was</em><em> </em><em>2</em><em>3</em><em>.</em><em>6</em><em>7</em><em>km</em><em>/</em><em>hr</em><em>.</em>

How to find a planet’s gravitational field strength using its radius?
grin007 [14]

The gravitational field strength is approximately equal to 10 N.

<u>Explanation:</u>

Gravitational field strength is the measure of gravitational force acting on any object placed on the surface of the planet. Generally, the mass of the object is considered as 1 kg.

So the gravitational field strength will be equal to the gravitational force acting on the object.

The formula for gravitational field strength is

g = \frac{F}{m}

Here g is the gravitational field strength, m is the mass of the object placed on the surface and F is the gravitational force acting on the object.

Since, the mass of any object placed on the surface of earth will be negligible compared to the mass of Earth, so the mass of the object is considered as 1 kg.

Then the g = F

And F =\frac{GMm}{r^{2} }

Here G is the gravitational constant, M is the mass of Earth and m is the mass of the object placed on the surface, while r is the radius of the Earth.

g = F = \frac{6 \times 10^{24} \times 6.67 \times 10^{-11}  \times 1}{(6.6 \times 10^{6}) ^{2} }

g = 0.977 \times 10^1= 9.77\ N

So, the gravitational field strength is approximately equal to 10 N.

What are two things that are infinite?
yaroslaw [1]

Answer:

Infinity = Never ending

Explanation:

The universe could be infinite, both in terms of space and time, but there is currently no way to test whether it goes on forever or is just very big. The part of the universe we are able to observe is finite, measuring about 46 billion light years in diameter.

The set of natural numbers is an infinite set. This kind of infinity is, by definition, called countable infinity. All sets that can be put into a bijective relation to the natural numbers are said to have this kind of infinity. This is also expressed by saying that the cardinal number of the set is aleph-naught (ℵ0).

Hope this helps. Mark as brainliest!
