Answer:
Real images are obtained using a converging lens or a concave mirror. The size of the real image depends upon the placement of the object. A virtual image is an upright image that is achieved where the rays seem to diverge. A virtual image is produced with the help of a diverging lens or a convex mirror.
Light shows duality i.e it shows properties of both particle as well as wave.
Answer: the answer is 23voltage
Explanation: because the voltage and time put together is 23
Density means how much mass is concentrated in the given 3d space .thus the more the density the more mass is occupied in the less space.. and thus the objects with lesser density floats on the object with higher density
Answer:
Explanation:
mass of displaced oil = 11 x .9
= 9.9 gm
9.9 x 10⁻³ kg
weight of displaced oil = 9.9 x 9.81 x 10⁻³ N
= .097 N .
buoyant force by oil = .097 N
weight of unknown metal = .1 x 9.8
= .98 N .
weight of metal in oil = .98 - .097
= .883 N .
=
