Answer:
D) All of these
Explanation:
The magnetic flux through a coil of wire is given by:
![\Phi = BA cos \theta](https://tex.z-dn.net/?f=%5CPhi%20%3D%20BA%20cos%20%5Ctheta)
where
B is the intensity of the magnetic field
A is the area enclosed by the coil
is the angle between the direction of B and the normal to the area of the coil
Therefore, we see that the magnetic flux depends on all these quantities:
A) the magnetic field
B)the orientation of the field with respect to the region through which it passes
C)the area of a region through which magnetic field passes
So, the correct answer is
D) All of these
That's a simple description of how <em>ultrasound</em> works.
Answer:
3 m/s
Explanation:
The computation of speed is shown below:-
We will compute the equation by using the law of conservation of momentum; also, the total momentum prior and following the collision must be conserved. Therefore we can write the equation is the following manner:-
![m_1 u_1 + m_2 u_2 = (m_1 +m_2)v](https://tex.z-dn.net/?f=m_1%20u_1%20%2B%20m_2%20u_2%20%3D%20%28m_1%20%2Bm_2%29v)
where the symbols represent
150 kg is the mass of spaceship 1 = m1
150 kg is the mass of spaceship 2 = m2
0 m/s is the initial velocity of spaceship 1 = u1
6 m/s is the initial velocity of spaceship 2 = u2
and v is the velocity of the 2 ships so that they can collide and combined together
For v we will get the following equation to reach the speed
![v=\frac{m_1 u_1 + m_2 u_2}{m_1+m_2}](https://tex.z-dn.net/?f=v%3D%5Cfrac%7Bm_1%20u_1%20%2B%20m_2%20u_2%7D%7Bm_1%2Bm_2%7D)
![=\frac{0+(150)(6)}{150+150}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B0%2B%28150%29%286%29%7D%7B150%2B150%7D)

Answer:
The answer is choice (3)
Explanation: Land materials do require more energy than water to raise their temperature by one degree, hence why water gets heated a lot easier than something like wood.
