Answer:

By the help of magnetic field of the earth

Explanation:

Compasses, also known as magnetic compass, help us primarily in navigating and determine position on the globe. The planet Earth has its own magnetosphere or magnetic field that is close with that of a magnetic poles, and this is how compass works. The compass needle aims north and south as it happens to coincide with the Magnetosphere or magnetic field.

What is the frequency if 140 waves pass in 2 minutes?

Paha777 [63]

Answer:

1.16 Hz

Explanation:

frequency, basically, is the number of wave on 1 second

so, in math we write like this

f = n/t

n = number of waves

t = time to do that (in sec)

f = 140/120 = 7/6 Hz

f = 1.16 Hz

Superman throws a 2400 n boulder at a villain. what horizontal force must superman apply to the boulder to give a horizontal acc

Ksenya-84 [330]

The boulder has a weight of W=2400 N. The weight of an object is the product between its mass m and the gravitational acceleration g:
$W=mg$
Rearranging the relationship, we can calculate the mass of the boulder:
$m= \frac{W}{g}= \frac{2400 N}{9.81 m/s^2}=244.6 kg$

We are told that Superman applies a horizontal force to this object, and as a result, the acceleration of the boulder is $a=12.0 m/s^2$ . We can find the force applied by using Netwon's second law of motion:
$F=ma=(244.6 kg)(12.0 m/s^2)=2935 N$

The best scientific reason for a scientist to accept a specific theory is?

lions [1.4K]

Answer:

The theory is supported by all the available observations and data.

Explanation: The scientific community will accept a theory when a sufficient body of evidence supports it. This includes experiments that refute other potential theories. Experiments should also be carried out that attempt to disprove the theory but cannot.

It should not matter who proposed the theory or who supports it, and instead should entirely be based on the quality and abundance of data supporting it.

Hope this helps!

I would say d because dyspareunia means painful sex so endometriosis, cyst, pelvic infections, and allergic reactions can all cause this.
