Answer:
Impulse = 0.5Ns
Explanation:
F = 50N
t = 0.01s
Impulse = ?
Impulse = Force * t,
Impulse = 50N * 0.01s = 0.5Ns
Answer:
Yep.. It's balanced and its a combination reaction
Explanation:
Reactants : S₈ + 24F₂
Product 8SF₆
<span>Seasons happen because Earth's axis is tilted at an angle of about 23.4 degrees and different parts of Earth receive more solar energy than others.</span>
The answers are:
1. Compaction - grains move closer together.
2. Foliation - parallel alignment of platy grains.
3. Recrystallization - grains take on a larger size.
4. Burial metamorphism - when a rock changes because of surrounding pressure.
Compaction produce rocks that have a tighter grain arrangement due to heat and pressure the rock undergoes. This process reduces the size of the rock.
Foliation occurs when pressure is put on one side of the grains more than any other direction. This creates platy structured rocks, which align under pressure.
Recrystallization is a process where the chemical composition a rock is changed. The mineral grains that are produced in this process are larger than the original grains.
Burial metamorphism occurs when rocks get buried deeper and deeper. They change due to the pressure from the overlying layers.
Since the initial and the final velocity are just equal, it is implied that the acceleration is zero. This means that the net force acting on the body is also zero. The horizontal force should be equal to the force of friction. The force of friction is equal to the product of the coefficient and the normal force.
Ff = (coefficient of friction) x Fn
The normal force is equal to the object's weight if the surface is horizontal.
Ff = (0.20) x (30 kg) x (9.8 m/s²) = 58.8 N
<span>
<span>Thus, the horizontal force exerted must be 58.8 N.
