Answer:
D :} if not that is A that what my thing say where correct
Explanation:
Answer:
energy that behaves as if they were particles
Explanation:
Answer:
angular acceleration.
Explanation:
Newton's law of universal gravitation states that the force of attraction (gravity) acting between the Earth and all physical objects is directly proportional to the Earth's mass, directly proportional to the physical object's mass and inversely proportional to the square of the distance separating the Earth's center and that physical object.
Generally, when a rigid body is made to rotate about a fixed axis, all the points in the body would typically have the same angular acceleration, angular displacement, and angular speed.
Answer:
Option c and d
Explanation:
The two mechanical devices which are used in laboratories for accurate measurement of small distances or small objects are calipers and micrometer.
Micrometer is a mechanical device used in laboratories like that of a screw gauge. It is used for the measurement of thickness of objects, length and the depth of the small objects which can be measured by holding the object in between the spindle and anvil of the micrometer.
Calipers is another mechanical device like that of vernier calipers used in laboratories for measurement of small distances, usually the distance between the opposing faces of the object. The measurement is usually taken on a digital display, a dial or a scale that is ruled.
The distance is measured by adjusting the tips of the caliper holding the object on a ruler.
