EXPLANATION:

The Tesla Roadster is an all-electric battery-powered four-seater sports car made by Tesla, INC. Tesla has said it will be capable of 0 to 60 MPH (0 to 97 km/h) in 1.9 seconds, which is faster than any street legal production car to date at its announcement in November 2017.

Explanation:

GIVEN THAT

INITIAL VELOCITY= 40m/s.

TO FIND MAXIMUM HEIGHT

H= U²/2G

SO H= 40²/20

H= 1600/20

Hmax= 80metre

TOTAL DISTANCE TRAVELLED = 2×Hmax

TOTAL DISTANCE TRAVELLED

2× 80 = 160 METRE

HOPE IT HELPS YOU

THANK YOU✌️

EXPLANATION:

TRUE DISPLACEMENT IS A VECTOR QUANTITY BECAUSE IT HAS A MAGNITUDE AS WELL AS DIRECTION

Due to DIFFERENCES in the WEIGHT of grain and husk

Explanation:

The wind blowing toward the mixture of husk and grain MAKES the husks fly , as husk is very light, leaving only GRAINS behind

Explanation:

It MEANS that the 1 cm-³ of brass will have the MASS of 8.4 GRAMS

Explanation:

While walking on ice, one should take SMALLER steps because the smaller the steps are, the smaller, the backward and forward forces, which prevents you, to fall or SLIP. ... If the applied force is larger (which is the taking of long steps), the lower will be the friction and vice VERSA..

ANSWER:

✍ Decantation is DEFINED as the separation process in which two immiscible liquids are separated. This is done by pouring out the clear upper layer of liquid.

✍ A common example is decantation of oil and vinegar. When a mixture of the two liquids is allowed to settle, the oil will FLOAT on top of the WATER so the two components may be separated. Kerosene and water can also be separated USING decantation.

Answer:

VALLABHBHAI Patel-first deputy PRIME MINISTER of INDIA

Answer:Simple Pendulum is a very small HEAVY metal bob suspended at a point from a firmly FIXED support using a single strand thread so that it OSCILLATES freely. The distance between the point of SUSPENSION and centre of bob is called the length of the pendulum.  

One OSCILLATION: One complete to and fro motion of the oscillating body is called one oscillation.  

Frequency: It is the number of oscillations made by the body in one second.

Time Period: It is the time taken by a body to complete one oscillation.

Hence, the Frequency and Time period are calculated as follows.

Time period = Time taken by the pendulum/Number of oscillations made by the pendulum.

10

20

​  

=2s

Frequency =1/Period

2

1

​  

=0.5Hz

Hence, the Time period and frequency are 2 seconds and 0.5 Hertz respectively.

Explanation:

Normally in the absence of rotation, the natural tenancy of gravity is to pull the Earth TOGETHER in the SHAPE of a sphere. However the Earth in fact bulges at the equator, and the diameter ACROSS the equatorial plane is 42.72 km more than the diameter from pole to pole. This is DUE to the rotation of the Earth.
