Answer:
8.33 m/s
Explanation:
v=d/s, velocity = displacement/ time
Answer:
20 ohms,100*2/10=20
Explanation:
since it as to be in parallel arrangement and connected in side by side due to same p.d in a cross each resistor
Answer: Option (C)
Explanation: Rock cycle plays an important role in the alteration of rocks from one form to another.
- Igneous rocks when undergoes high temperature and pressure condition, it transforms into a metamorphic rock.
- Sedimentary rocks are formed from the sedimentation and consolidation of sediments
- Igneous rocks are formed due to the crystallization of magma.
Hence the correct answer is option (C)
Answer:
False
Explanation:
It is not necessary, that when the initial speed of the object is zero then it must be at origin.
It may be the object starts motion from the left of origin.
Energy stored in the capacitor= 2.2 x 10⁻¹⁰ J
Explanation:
The energy stored in the capacitor is given by
E= 1/2 q V
E= energy stored
q= charge= 7.6 x 10⁻¹¹ C
V= potential difference=5.8 V
so energy stored= E= 1/2 (7.6 x 10⁻¹¹) (5.8)
Energy stored= 2.2 x 10⁻¹⁰ J
