Achievement is one of the psychosocial needs identified by the psychologist Henry Murray. The motivation to achieve is a need or desire to attain a certain standard of excellence. People with high achievement motivation don’t just try hard; they are also realistic in the goals they set for themselves. People with low achievement motivation set goals that are either very easy to attain or too ambitious.
Answer:
Explanation:
Given
First you travel 4 mi North
position vector for this displacement is given by
Now you travel 5.31 mi w.r.t is given by
Now you travel 1.1 mi in a direction North of east; Position vector w.r.t is given by
Thus Position Vector of w.r.t starting Point
For angle
Answer:
18 m
Explanation:
y = 10x − 5/9 x²
When the projectile lands, y=0:
0 = 10x − 5/9 x²
0 = x (10 − 5/9 x)
x = 0, 18
The range of the projectile is 18 m.
Answer:
Explanation:
Temperature of the gas is defined as the degree of hotness or coldness of a body. It is expressed in units like and
These units of temperature are inter convertible.
We are given:
Temperature of helium =
The conversion used for the temperature from Kelvin to Fahrenheit is:
As we know that, or,
...........(1)
Now put the value of temperature of Kelvin in (1), we get:
Thus the temperature of helium is
Answer: (a)
Explanation:
Given
Mass of large truck is 4M with velocity V
Mass of small car is M which is at rest
After the collision car and truck stick together
Conserving momentum
For elastic collision, the velocity of the center of mass remains the same as the momentum is conserved and there is no acceleration involved.
So, for elastic collision velocity
