You must first convert minutes to seconds so 10*60=600
Then multiply the number of seconds by the speed so 600*2=1200 m

Answer:
2917.4 m/s
Explanation:
From the question given above, the following data were:
Gravitational acceleration of the Moon (g) = 0.25 times the gravitational acceleration of the earth
Radius (r) of the Moon = 1737 Km
Escape velocity (v) =?
Next, we shall determine the gravitational acceleration of the Moon. This can be obtained as follow:
Gravitational acceleration of the earth = 9.8 m/s²
Gravitational acceleration of the Moon (g) = 0.25 times the gravitational acceleration of the earth
= 0.25 × 9.8 = 2.45 m/s²
Next, we shall convert 1737 Km to metres (m). This can be obtained as follow:
1 Km = 1000 m
Therefore,
1737 Km = 1737 Km × 1000 m / 1 Km
1737 Km = 1737000 m
Thus, 1737 Km is equivalent to 1737000 m
Finally, we shall determine the escape velocity of the rocket as shown below:
Gravitational acceleration of the Moon (g) = 2.45 m/s²
Radius (r) of the moon = 1737000 m
Escape velocity (v) =?
v = √2gr
v = √(2 × 2.45 × 1737000)
v = √8511300
v = 2917.4 m/s
Thus, the escape velocity is 2917.4 m/s
Answer:
A student becomes negatively charged because of the friction between his socks and the carpet. ... The electrons get rubbed and move towards the carpet so the carpets electrons move away and the student becomes negatively charged.
Answer:
Two
Explanation:
A neutral point is a point in the magnetic field of a bar magnet where the resultant magnetic field intensity is zero
The neutral point is formed in the region of the combined magnetic field where the magnetic field from the bar magnet is balanced by the horizontal component from the Earth's magnetic field
Two neutral points are formed adjacent to the north and south poles of a bar magnet when the south pole of the bar magnet points in the magnetic north pole of the Earth with the north pole of the bar magnet pointing towards the south pole of the Earth's magnetic field
Two neutral points are also formed on the west and eastern facing sides of a bar magnet when the north pole of the magnet is pointing to the magnetic north of the Earth's magnetic field and the south pole of the bar magnet points south
Therefore, two neutral points are formed for each orientation of the bar magnet when placed horizontally in the Earths magnetic field with the poles of the magnet facing the North and South poles direction of the Earth's magnetic field.
