If a lava flow at Earth's surface has a basaltic composition, then the rock type that would flow is a basalt. This is because the rock would rapidly cool resulting a rock that is fine grained texture. Basalt is a rock that is dark in color and has a fine texture. It is primarily made up of pyroxene and plagioclase minerals. Most of this type of rock is found on the ocean basins of the Earth's surface. Due to its abundances, it has a wide different uses. Typically it is used as an aggregate in construction needs. It used as road base, asphalt aggregate, concrete aggregate and railroad ballast. Also, this rock is very abundant in the moon and in mars.

Option (ii) B is the correct option. The object on the moon has greater mass.

To resolve this, utilize the formulas Force = Mass * Acceleration.

The equation can be used to find the mass given the force in Newtons, using 9.8 m/s² for the acceleration of gravity of the earth and 1.6 m/s² for the moon.

Calculating the mass on earth:

30 N = 9.8 m/s² * mass

This results in a mass of 3.0 kg for the object on Earth.

Calculating the mass of the moon:

30 N = 1.6 m/s²2 * mass

Thus, the moon's object has a mass of 19. kg.

This can be explained by the fact that the earth has a stronger gravitational pull than the moon, producing more force per kilogram of mass. As a result, the moon's mass must be bigger to produce the same amount of force at a lower acceleration from gravity (1.6 m/s² vs. 9.8 m/s²).

Indicate whether the following statements are always true or can be false. An object's velocity will change if a net force acts

Sergio [31]

Answer:

1-An object's velocity will change if a net force acts on the object. (True)

2-In order not to slow down, a car moving at a constant velocity needs a small net force applied. (False)

3- The net force which acts on an object which remains at rest is zero. (True)

4- If an object's speed does not change, no net force is acting on the object.(True)

5- If two objects are under the influence of equal forces, they have the same acceleration. (False)

6- During the collision of a car with a large truck, the truck exerts a greater force on the car than the car exerts on the truck.(False) (Newton Third Law)

A stuffed toy with a mass of 0.900 kilograms sits on the edge of a bed at a height of 0.830 if the toy falls off the bed what wi

Olenka [21]

Mechanical energy (ME) is the sum of potential energy (PE) and kinetic energy (KE). When the toy falls, energy is converted from PE to KE, but by conservation of energy, ME (and therefore PE+KE) will remain the same.

Therefore, ME at 0.500 m is the same as ME at 0.830 m (the starting point). It's easier to calculate ME at the starting point because its just PE we need to worry about (but if we wanted to we could calculate the instantaneous PE and KE at 0.500 m too and add them to get the same answer).

At the start:

ME = PE = mgh
ME = 0.900 (9.8) (0.830)
ME = 7.32 J
