Answer: (d)
Explanation:
Given
Mass of the first ram 
The velocity of this ram is 
Mass of the second ram 
The velocity of this ram 
They combined after the collision
Conserving the momentum
![\Rightarrow m_1v_1+m_2v_2=(m_1+m_2)v\\\Rightarrow 49\times (-7)+52\times (9)=(52+49)v\\\Rightarrow v=\dfrac{125}{101}\ m/s \quad[\text{east}]](https://tex.z-dn.net/?f=%5CRightarrow%20m_1v_1%2Bm_2v_2%3D%28m_1%2Bm_2%29v%5C%5C%5CRightarrow%2049%5Ctimes%20%28-7%29%2B52%5Ctimes%20%289%29%3D%2852%2B49%29v%5C%5C%5CRightarrow%20v%3D%5Cdfrac%7B125%7D%7B101%7D%5C%20m%2Fs%20%5Cquad%5B%5Ctext%7Beast%7D%5D)
Momentum after the collision will be
Therefore, option (d) is correct
Answer:
The answer is D.) 90
Explanation:
the electromagnetic wave is a transverse wave. the electric field makes an angle of 90° with the magnetic field. both these fields, in turn, make an angle of 90° with the direction of movement of the wave.
Latitude, elevation, ocean currents, topography, and prevailing winds. There's probably a few others but these are the most important.
The total distance that is traveled is 12 inches.
<h3>
What is the distance?</h3>
We know that distance is a scalar quantity. The term distance only has to do with the difference between two points. The direction is not taken into cognizance when we are discussing the distance that has been covered.
As we have said that distance is a scalar quantity, it the follows that the process of obtaining the total distance can only be algebraic given that we could directly add all the distance covered by the ant in order to obtain the total distance of the ant.
Now, we can see that the ant starts at the 17-inch mark, crawls to the 21-inch mark, then moves to the 8-inch mark. The total distance covered is obtained from; (21 - 17) + 8 = 12 inches.
