Answer:
the first one looks like a spiral galixy
the 2nd one looks like a lenticular galixy ?? (im pretty sure but not 100%)
the 3rd one looks like a elliptical galixy
Explanation:
Answer:
1404 m
Explanation:
Given that
Depth of ocean = 780 fathoms
Given that
1 fathoms = 1.8 metes
1 fathoms = 1.8 m
Therefore 780 fathoms
1 x 780 fathoms = 1.8 x 780 m
780 fathoms = 1.8 x 780 m
780 fathoms = 1404 m
Therefore the depth of the ocean in meters will be 1404 m.
Note- A fathom is a unit of length equal to 6 feet (1.828 m) in the imperial and U.S. customary systems, especially used to measure water depth in the ocean. In such an imperial fathom there are two yards (6 feet).
The expected time period between the observations of lightning and thunder would be 22.5 s.
How to calculate the time of sound waves?
The time taken by sound to reach a certain position can be calculated by the speed formula,
Where,
- speed = 0.343 km/s
- distance = 7.5 km
- time = ?
Put the values in the formula,
Therefore, the expected time period between the observations of lightning and thunder would be 22.5 s.

Answer:
Controlled for useful work
Explanation:
Answer:
162 N
Explanation:
Since the handbag weighs 162 N, from Newton's third law of motion, we know that to every action, there is an equal and opposite reaction. Thus, it means the force by each student arms Carrying the bag will be 162 N.
Since both handles of the bag are at same inclined angle of 60°, then the force in each students arm will be equal and thus;
F_each arm = 162 N
