**Answer:**

43.80°

**Explanation:**

The side of the equilateral triangle is given as 8 cm

The area of the equilateral triangle

Magnetic field

Magnetic flux

We know that

So

Answer:

Pressure = Density x Gravity acceleration x Height

Density of water = 1000 Kgm^-3

Gravity acceleration = 9.8 ms^-2

So it is 4.50.

Hope this helps and please mark me brainliest!

Kinetic energy is related to an object's mass and velocity. The greater the velocity, the greater its kinetic energy will be if the mass remains constant. (so, the 10 m/s one)

**Kepler's first law - sometimes referred to as the law of ellipses - explains that planets are orbiting the sun in a path described as an ellipse. ... The resulting shape will be an ellipse. An ellipse is a special curve in which the sum of the distances from every point on the curve to two other points is a constan**
