Explanation:
It is given that,
Mass of the car, m = 875 kg
Initial speed of the car, u = 30 m/s
Brakes are applied i.e. v = 0
The car skids for 5.60 s in the positive x - direction before coming to rest, t = 5.6
(a) Acceleration of the car, 
(b) Force, F = ma
F = -4681.25 N
So, the force of 4681.25 N is acting on the car.
(c) Let x is the distance covered by the car. So,
x = 84.11 meters
So, the distance covered by the car is 84.11 meters. Hence, this is the required solution.
The transition zone between the crust and mantle is called as mohorovicic discontinuity.
The mohorovicic discontinuity was discovered by Andrija Mohorovicic in the year of 1909. The Moho lies at the depth of 35km beneath the continents and 8km beneath the oceanic crust. The Moho separates both the continental crust and the oceanic crust from underlying mantle. The Moho lies almost entirely within the lithosphere, only beneath the Mid Oceanic Ridge does it define lithosphere and asthenosphere boundary. Immediate above the Moho velocity of the P wave is 6km/sec and just below the Moho it becomes 8km/sec. Moho is characterised by up to 500km thick.
The Mohorovicic Discontinuity marks the lower limit of Earth's crust. It occurs at an average depth of about 8 kilometers beneath the ocean basins and 32 kilometers beneath continental surfaces. Mohorovicic was able to use his discovery to study thickness variations of the crust.
Mohorovicic discontinuity is the layer which is between the earth's crust and mantle. It's density ranges from 3.3 to 3.7.

Answer: It encourages scientists to give convincing evidence for the results
Answer:
Properties of minerals are:
B) made of just one substance
C) made of at least two substances
Explanation:
Minerals & their Properties
Minerals are defined as the naturally occurring, solid inorganic chemical compounds. They have an orderly internal structure with definite chemical composition.
Fossils usually contain single or multiple minerals such as Calcite, Quartz, Phosphate etc. Sometimes minerals are visible in the crystalline form in fossils. So, we cannot say that minerals are made of fossils. Instead, fossils can be made of minerals.
According to the prime and standard definition given by scientists, minerals are usually composed of chemical compounds or multiple compounds such a Halite which composed of Sodium and Chlorine elements. But they can be made of just one substance or element.
Now talking about the tiny grains of sand, that are made of minerals. So, instead of saying that minerals are composed of tiny grains of sand, we should say that sand is made of minerals. The most common mineral which forms sand is Quartz. Sand has a versatile mixture of substances besides minerals.
