Answer:
Force, F = 124 N
Explanation:
We have,
Mass of bicycle is 12 kg and mass of rider is 50 kg
Total mass of the system is 12 kg + 50 kg = 62 kg
Acceleration of the system is 2 m/s²
It is required to find the force required to accelerate the system. The force acting on an object is given by :
So, the force of 124 N is acting on the system.
Answer: v = 5.79 * 10^10m/s.
Explanation: By using the work-energy theorem, we know that the work done on the electron by the potential difference equals the kinetic energy of the electrons.
Mathematically, we have that
qV = 1/2mv²
q= magnitude of an electronic charge = 1.609*10^-16c
V= potential difference = 95v
m = mass of an electronic charge = 9.11* 10^-31kg.
v = velocity of electron.
Let us substitute the parameters, we have that
1.609*10^-16 * 95 = (9.11*10^-31 * v²) /2
1.609*10^-16 * 95 * 2 = 9.11*10^-31 * v²
305.71 * 10^-16 = 9.11 * 10^-31 * v²
v² = 305.71 * 10^-16/ 9.11 * 10^-31
v² = 3.355 * 10^21.
v = √3.355 * 10^21
v = 5.79 * 10^10 m/s
Answer:
Between -35 degrees C and 355 degrees C
Explanation:
At any temperature between, but not including the freezing and boiling points, the substance would be in its liquid state.
Answer:
there move slower
Explanation:
because when heated the molecules of the matter[liquid]move faster but when cooled,they move slow or they do not.
The distance covered is 4d.
<h3>
What is the distance?</h3>
- Distance is a measure of how far apart two objects or locations are using numbers.
- The distance can refer to a physical length or an estimate based on other factors in both daily language and physics (e.g. "two counties over").
- The terms "distance from A to B" and "distance from B to A" are frequently used interchangeably.
- A distance function or metric is a technique to describe what it means for components of space to be "near to" or "far away" from each other in mathematics.
- It is a generalization of the idea of physical distance. Distance is a non-numerical unit of measurement in psychology and the social sciences; psychological distance is the separation of an object from itself along dimensions including time, space, and isolation.
We know that
the magnetic field is inversely proportional to distance.
