Answer:

1.    B)    magnet

2.   C)    motor

Explanation:

1)

In Orsted's observation he found that when few small iron piece is placed near the current carrying wires then all the iron pieces will arrange themselves in the circular loop.

This arrangement is always due to the magnetic field produced by the current carrying wire. So as per his observation the current carrying wire will behave like a magnet.

2)

Michael Faraday explained about the Electromagnetic induction laws and he worked on the theories given by Orsted.

So as per his theory when magnetic flux linked with a conductor changes then it will induce electric current.

So his inventions are based upon rotating device

So it is Electric Motor

Describe the factors that cause static friction between two surfaces to increase.
maw [93]

Answer : The static friction depends on two factors

1. Roughness of the surface

2. Force

Explanation : Friction occur when surface is not smooth.

The formula of friction is

F= \mu mg

Static friction depends on the roughness of the surface and force which is trying to push to object along the surface.

Static friction is caused by the attraction between two surfaces that are in contact.  when the surface will rough and the object will heavier then the force will be larger.

f (is the focal length of the lens) = ? 
p (is the distance from the object to the lens) =15.8 cm
p' (is the distance from the image to the spherical lens) = 4.2 cm

</span><span>Using the Gaussian equation, to know where the object is situated (distance from the point).
</span>
\frac{1}{f} = \frac{1}{p} + \frac{1}{p'}
\frac{1}{f} = \frac{1}{15.8} + \frac{1}{4.2}
\frac{1}{f} = \frac{2.1}{33.18} + \frac{7.9}{33.18}
\frac{1}{f} =  \frac{10}{33.18}
Product of extremes equals product of means:
10*f = 1*33.18
10f = 33.18
f =  \frac{33.18}{10}
\boxed{\boxed{f = 3.318\:cm}}\end{array}}\qquad\quad\checkmark

in a softball game, a batter hits the ball at the velocity of 27m/s and angle of 40 shown below. What is the maximum range of th
Nata [24]

Answer:

R = 73.25 m

Explanation:

We have,

Initial speed of the ball is 27 m/s

It is projected at an angle of 40 degrees

The maximum range of the ball is given by :

R=\dfrac{u^2\sin2\theta}{g}

Plugging all the values we get :

R=\dfrac{(27)^2\sin2(40)}{9.8}\\R=73.25\ m

So, the maximum range of the ball is 73.25 m
