The correct answer is the one with 45000 kg*km/hr.
the formula is p = m*v 
 900 *50/hr  giving u 45000 
I know this is the correct answer because i have already turned it in and got a 100%.

Answer: The magnitude of momentum will be equal to 12,500 kg m/s.

Explanation:

Momentum is defined as the product of the mass of the object and velocity of the object.

Mathematically,

p=mv

where, p = momentum

m = mass of the object ( in kg) = 900 kg

v = velocity of the object ( in m/s) = 50km/hr = \left(\frac{50\times 1000}{3600}\right)m/s

Putting values in above equation, we get:

p=900kg\times \left(\frac{50\times 1000}{3600}\right)m/s=12500kg.m/s

Hence, the magnitude of momentum will be equal to 12,500 kg m/s.

How will the motion of the arrow change after it leaves the bow?
Pavel [41]

The string moves to the right, as it restores its original position with the median plane of the bow. As a result, the string "pulls" on the arrow with a force F2. 2. The tip of the arrow T moves slightly to the left.

Alchen [17]

Answer:

Distance between two adjacent wave crests = 24m

Explanation:

Distance= speed × time

Distance traveled by waves in 60 seconds (15 crests)= 15 × distance

15 × distance = 6,0 (meters/second) × 60 seconds

distance = (360 meters) / 15 = 24 meters (between two adyacent waves)

Will an electromagnet be obtained if steel is placed inside the solenoid?​
iogann1982 [59]

Answer:A solenoid is a simple electromagnetic device consisting of a coiled electric wire, wrapped in a 3D circular pattern. When electric current is passed through the wire, the solenoid acts like a magnet with N and S poles at the ends of the coil.

When a ferromagnetic material rod is permanently placed inside the solenoid, the metal greatly increases the magnetic effect and becomes a permanent electromagnet. Moreover, it can also be used as an electrical switch by drawing in or pushing out a ferromagnetic material like an iron rod. Depending on the directions of the rod and the electrical current the switching action takes place.

Given figure  represents the solenoid as electromagnet and the switching action.
