Answer:
B. man with a beard
Explanation:
it is not a genetic mutation because it is completely natural and common unlike the other options.
Answer:
Explanation:
Temperature is directly proportional to thermal energy of a body.
Thermal energy is one of the numerous forms of kinetic energy which dependent on the motions of the particles in a body.
When the temperature of a body increases, it possess more kinetic thermal energy. In this case, the molecules of the body gains more energy and begins to vibrate until they attain maximum kinetic energy.
The higher the temperature the more the kinetic energy.
Answer:
A.) a bicycle moving at a constant speed on a straight, level road.
Explanation:
Force is given by the multiplication of mass and acceleration.
Mathematically, Force is;
Where;
F represents force measured in Newton.
m represents the mass of an object measured in kilograms.
a represents acceleration measured in meter per seconds square.
In Physics, when the net force acting on a body or an object is equal to zero (0); the body or object is said to be in a state of equilibrium because it is not accelerating. This ultimately implies that, an object whose net force is equal to zero is either moving with a constant speed or the object is static i.e not moving at all.
In this scenario, the situation in which the net force on the object is equal to zero would be a bicycle moving at a constant speed on a straight, level road because it is at equilibrium and as such its resultant force is equal to zero.
Answer:
The time spent in air by the car is 2.19 s
The height of the cliff is 58.5 m
Explanation:
Given;
initial velocity of the car, u = 16 m/s
horizontal distance traveled, R = 35 m
The horizontal distance or range of a projectile is given as;
R = vt
where;
t is the time spent in air by the projectile
t = R/v
t = 35 / 16
t = 2.19 s
The height of the cliff is given as;
h = ut + ¹/₂gt²
h = (16 x 2.19) + ¹/₂(9.8)(2.19)²
h = 58.5 m
The correct answer to the question is - Deposition i.e the process by which a gas changes to a solid is called deposition.
EXPLANATION:
There are various thermal processes of state or phase change in which matter in one state is converted into matter in another state.
Deposition is the type of thermodynamic process of state or phase change in which a gaseous substance is directly converted into corresponding solid substance without entering into liquid phase.
During this process, the loss of thermal energy from gas is very fast. Hence, the gas directly enters solid phase without undergoing into liquid phase.
This process is just the opposite process of sublimation where a solid is converted into gas directly. That's why this process is also known as desublimation.
For instance, conversion of water vapor into ice.
