Six centimeters equal to about two inches
Since
Force (weight) = mass x acceleration (gravity)
To determine acceleration, the formula will be:
Acceleration = Force / mass
Given are:
F = 10 N
M = 2kg
A = ?
Solution:
1. A = F/M
2. A = 10 kg*m/s2 / 2kg
3. A = 5 m/s2
Answer:
153.0815W/m.K
Explanation:
Heat transferred in phase is changed is expressed as:
(m-mass, Q-heat, L-Latent heat of phase change)
Latent heat is the heat required to change the phase of 1kg of the material.
#The rate of heat flow(by conduction) per unit time:
#Heat flowing through melting ice.
To solve for k:
The thermal conductivity k of the metal is 153.0815W/m.K
Answer:
B
Explanation:
Transformation of energy involves conversion of energy from one form to another for example our movement around involves the conversion of chemical energy stored in the food we eat to other forms of energy such as kinetic energy for the movement, electrical energy in the neurons for impulses and others
The ball posses gravitational potential energy since it is held at a displacement to the ground ( zero point) and when released, the gravitational potential energy is converted to kinetic energy which leads to the fall of the ball until it is at zero displacement to the earth. The board likewise when bent to its maximum extent stored elastic potential energy as a result of the partial displacement of its constituent particle provided it is not stretch beyond its elastic limit which can lead to deformation of the board and the elastic potential energy lost.
Answer:
The correct answer is c
Explanation:
In these two different models of movement of the planets
Ptolemy raises the Earth as the center of the solar system
In the Copernicus system, it poses the Sun as the center of the solar system.
Copernicu's system was accepted for giving a simpler and more complete explanation of the problem
The correct answer is c
