Answer:
Explanation:
When I hear "transformation of energy from one form to another", I think of the system exchanging energy with its surroundings. A transformation of energy simply means the system contains a different type of energy than it previously did. One example I can give is a ball. A ball at the top of a hill has a maximum potential energy. If given the chance to roll, it will go to a minimum state of potential. This will convert all of the potential energy into pure kinetic energy, once it reaches the bottom of the hill of course.
Therefore the world's record high temperature of 134.0°F (56.7°C) is held by Furnace Creek Ranch in Death Valley, California. That global high temperature was attained on July 10, 1913.
Answer: ratio = 3.14 × 10³⁵
Explanation:
From Newtons law of Universal Gravitation;
Every object in the universe is attracted to every other object
F = (Gm₁m₂)/r²
G = 6.67 X 10⁻¹¹ N-m²/kg²
M₁= mass of one object
M₂= mass of second object
r = distance from center of objects
q = charge = 3.2 x 10⁻¹⁹C.
- Calculating the gravitational force;
Fg = (Gm₁m₂)/r² = (Gm²)/r²
which is = (6.67×10⁻¹¹ × (6.64×10⁻²⁷)²) / r²
= (2.94 × 10⁻⁶³) / r²
- Calculating the electric force;
Fe = (Kq₁q₂) / r² = K q² / r² = (9×10⁹ × (3.2 × 10⁻¹⁹)² / r²
Fe = 9.22 × 10⁻²⁸ / r²
comparing the ratio of both forces we have;
Fe/Fg = (9.22×10⁻²⁸/r²) ÷ (2.94×10⁻⁶³/r²)
r² cancels from the above expression, which gives;
ratio as 3.14 × 10³⁵
Q.1
Answer . Momentum = mass x velocity
Momentum/mass = velocity
5/0.8 = velocity
6.25 m/s = velocity
Q.2
Answer . F = ma => a = f/m => a = 7/3.2 => a = 2.1875m/s²
