Answer and Explanation:

The main source of earth magnetic field is the metals and iron present in earth crust these metals are mainly found in liquid state in earth crust and we know that whenever there is spinning of these liquid metals then there will magnetic field generate, So the main source of earth magnetic field is the metals present in earth crust.

Answer:

Explained

Explanation:

The core of the Earth is composed of molten metals mostly iron and nickel.  These molten metals are in continuous motion. Thus, generating a very strong current convectional current. This in turn produces magnetic field around Earth. These convectional currents are caused due to heat escaping the earth's core. This magnetic field acts as a barrier against solar wind trying enter the earth's atmosphere.

A student was trying to find the relationship between mass and force. He placed four different masses on a table and pulled them
Gwar [14]

Answer:

B. There is a direct proportion between the mass and force listed in the table.

Explanation:

From the table, the values of force increases with increase in the value of mass.

if 5kg=25 N

Finding the contant of proportionality k;

k=25/5=5

thus M=k(F)...........where M is mass in kg and F is force in newton, then

M=5F

This show that for every value of mass, we get the value of Force if we multiply by a contant k=5

This means there is a direct proportionality relation between mass and force in the table.

A hockey puck slides across the ice with an initial velocity of 7.2 m/s. It has a deceleration of 1.1 m/s2 and is traveling towa
dezoksy [38]

Answer:

0.74 s

Explanation:

We can solve the problem by using the following SUVAT equation:

d = ut + \frac{1}{2}at^2

where

d = 5.0 m is the displacement

u = 7.2 m/s is the initial velocity

a = -1.1 m/s^2 is the acceleration (which is negative since it is a deceleration)

t is the time

Substituting numbers into the equation, we find:

5.0 = 7.2 t -0.55t^2\\0.55t^2 -7.2t + 5.0 = 0

This is a second-order equation, whose solutions are given by:

t=\frac{-(-7.2) \pm \sqrt{(-7.2)^2-4(0.55)(5.0)}}{2(0.55)}

And the solutions are

t = 0.74 s

t = 12.36 s

The solution we are looking for is the first one, because it corresponds to the first time at which the hockey puck has travelled the distance of 5.0 m, reaching the goal.
