Answer:
5.59 m/s
Explanation:
We are given;
Mass = 110 kg
Initial velocity: u = 13.41 m/s
Force = 615 N
Time(t) = 1 s
Now, formula for force is;
Force = mass x acceleration
Thus;
615 = 110 × acceleration
Acceleration(a) = 615/110 = 5.591 m/s²
Now, using Newton's first law of motion, we can find acceleration (a). Thus;
v = u + at
v = 13.41 + (5.591 × 1)
v ≈ 19 m/s
So, change in velocity is;
Final velocity(v) - Initial velocity(u) = 19 - 13.41 = 5.59 m/s
Newton's 2nd law of motion:
Force = (mass) x (acceleration)
29 N = (5 kg) x (acceleration)
Divide each side
by 5 kg : 29N / 5kg = acceleration
5.8 m/s² = acceleration
Answer:
The converging lenses make the eyes appear larger, and the diverging lenses make the eyes appear smaller.
Explanation:
Diverging lenses are placed in the path of a beam of parallel rays that allow the rays to diverge after refraction.
Glasses use diverging lenses to correct for nearsightedness a diverging lens will diverge light before it reaches the eye.
Farsightedness refers to the inability to see close objects for which a converging lens is required to increase power.
In the given situation,
<u>the converging lenses make the eyes appear larger, and the diverging lenses make the eyes appear smaller</u>
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.
