Answer:
The next high tide will happen at 6 pm.
Explanation:
The rotation of the Earth and the translation movement of the Moon (ie the Moon's movement around the Earth), in addition to the gravitational force, contribute to the formation of the tides. The high tide will occur on the face of the Earth which is facing / facing the Moon; the low tide will occur on the faces that are forming approximately an angle of 90 ° with respect to the Moon.
There are usually two periods of high tide and two periods of low tide over a day. The interval between high tide and low tide is approximately 6 hours.
Besides the gravitational force exerted by the Moon, the tide is also influenced by the gravitational force that the Sun exerts on the Earth. The influence of the Sun is smaller due to its distance, but it can also be noticed depending on the phase of the Moon.
Answer:
1250kg
Explanation:
Given parameters:
Acceleration = 1.2m/s²
Force = 1500N
Unknown:
Mass on the vehicle = ?
Solution:
According to newton's second law of motion:
Force = mass x acceleration
Since mass is the unknown, insert the parameters and solve;
1500 = mass x 1.2
mass = 
= 1250kg
