Answer:
5 m/s
Explanation:
Given that,
A vehicle is moving with 20m/s towards the east and another is moving 15m/s towards the west.
It is assumed to find the resultant velocity of the vehicle. Let east side is positive and west is negative. So,
Hence, the resultant velocity of the vehicle is equal to 5 m/s.
Answer:
Explanation:
False --> A cylindrical capacitor is essentially a parallel plate capacitor rolled into a tube. This is because a cylindrical capacitor comprises two cylinders.
False --> The dielectric constant indicates the distance by which the two plates of a capacitor are separated.
True --> The charge on a capacitor increases quickly at first, then much more slowly as the capacitor charges. This is because the charge on the capacitor increases exponentially.
False --> The voltage across a capacitor in an RC circuit increases linearly during charging. This is because the voltage increases exponentially.
True --> One of the principal purposes of a capacitor is to store electric potential energy.
True --> A capacitor charges rapidly when connected to an RC circuit with a battery. This is because a cylindrical capacitor is basically a parallel plate capacitor rolled into a tube.
Answer:
The mass is 
Explanation:
Generally from Newton law for the first block
=> 
For the second block the force is 
and the acceleration is 
So from Newton law
=> 
substituting for a
=> 
=>
Octopus
1. Octopus/Squid. These similar creatures are both cephalopods and have three hearts in total, one systematic to go along with two “gill hearts” that force blood to the gills.
