Answer:

There is constant cosmic background radiation.

Explanation:

The detection of constant cosmic background radiation provided an evidence for the Big Bang theory. The cosmic microwave background radiation is considered as remnant radiation of the early stages of the universe. The cosmic microwave background radiation was detected in all the directions. The average temperature of the background radiation is 3 K.

The "Big Bang" theory is the best known explanation for the constant cosmic background radiation.

Real scientists don't use evidence to support their theories.

Real scientists propose theories to explain the observed evidence. After that, they try every way they can think of to prove that the theory is False.

Two cyclists, 50 miles apart, start riding toward each other at the same time. One cycles 4 times as fast as the other, and they

Bond [772]

Answer:speed of slower cyclist is 5 mph

Explanation:

Given

Distance between two cyclist is 50 miles

One cycle is 4 times fast as other

Speed of slower cyclist is r miles per hour

speed of faster cyclist is 4 r

they meet after t=2 hr

Distance traveled by fast cyclist is $x=2\times 4r$

Distance traveled by slower cyclist is $y=2\times r$

$x+y=50$

$2\times 4r+2\times r=50$

$8r+2r=50$

$10r=50$

$r=5 mph$

$4 r=20 mph$

speed of slower cyclist is 5 miles per hour

Draw a winding path that covers a distance of 70 miles and finishes with a displacement 20 miles soulthwest of the starting poin

EleoNora [17]

Distance is indeed a scalar amount that also refers to "how the ground an object has encased", and the Displacement is a vector thing that leads "to the extent to which an object is located", and the further calculation can be defined as follows:

Given:

distance= 70 miles

displacement = 20 miles

Displacement formula: $\bold{Velocity = \frac{displacement}{time}}$

Distance formula: $\bold{Distance = speed \times time}$

If i punch my self and it will hurt am i weak or strong

Natasha2012 [34]

Answer:

You're strong.

Explanation:

I've been thinking of this for quite a while, and I realized that your body has a certain limit to how much pain it can take. So, punching yourself extremely hard will cause pain, because that's your body's reaction to immense pressure being put on it. But, the fact that you punched yourself so hard that it hurts, shows that you are capable of applying so much pressure; therefore, you are strong.
