Answer:
The value of d is 183.51 m.
Explanation:
Given that,
Speed of car = 34.0 m/s
Suppose The car race in the circle parallel to the ground surface is at an angle 40°
The radius of circular path
Normal force acting on the car = N
We need to calculate the value of d
Using component of normal force
The horizontal component of normal force is equal to the gravitational force.
....(I)
The vertical component of normal force is equal to the centripetal force
.....(II)
Divided equation (I) by equation (II)
Put the value of g
Put the value into the formula
Hence, The value of d is 183.51 m.
Answer:
it takes the shape and size of the container that it is in
Explanation:
Answer:
A) Plasticine
Explanation:
Palestine doesn't take much strain to harden and its strain rate isn't sensitive, therefore making it perfectly plastic.
The nucleus is the genetic store of the cell's information. It also controls the functions of the cell
Answer:
The value of acceleration equals
Explanation:
The distances covered in each of the three phases are calculated as under
1) Distance covered in accelerating phase for a period of 5 minutes or 300 seconds ( 1 minute = 60 seconds)
Using second equation of kinematics
2) Distance covered in 5 minutes while travelling at a constant speed which is The speed after 5 minutes of travel is obtained by first equation of kinematics as
Thus distance traveled equals
3)
The phase when the car stops the distance it covers during this phase can be obtained using third equation of kinematics as
Now the sum of equals 10 kilometers or 10000 meters.
Thus we get
