you can easily remember the trig functions with this acronym:
SOH-CAH-TOA
S: Sine
O: Opposite
H: Hypotenuse
C: Cosine
A: Adjacent
H: Hypotenuse
T: Tangent
O: Opposite
A: Adjacent
Answer:
0.88
Explanation:
velocity (v) = 22 m/s
radius (r) = 56 m
acceleration due to gravity (g) = 9.8 m/s^{2}
What minimum coefficient of static friction between the tires and road is necessary for the car to round the curve without slipping?
for the car to successfully go round the curve, the frictional force must be equal to or greater than the normal force, therefore
Normal force = frictional force
ma = μmg
where
- μ = coefficient of friction
- g = acceleration due to gravity
- a = = = 8.6
- putting in all required values the equation now becomes
8.6m = μm x 9.8
8.6 = 9.8 x μ
μ = 8.6/9.8 = 0.88
Answer:
Velocity will be
Explanation:
We have given mass of alpha particle m = 4 u
Charge on alpha particle
Charge on thorium particle
Diameter is given as d = 15 fm
So radius
Potential energy is given by
From energy conservation
Answer:
Explanation:
Given
diameter of spacecraft
radius
Force of gravity =mg
where m =mass of object
g=acceleration due to gravity on earth
Suppose v is the speed at which spacecraft is rotating so a net centripetal acceleration is acting on spacecraft which is given by
Answer:
6400 W (or) 6.4 KW
Explanation:
Formula we use,
→ P = I²R
Let's solve for the power of device,
→ P = I²R
→ P = (8)² × 100
→ P = 64 × 100
→ [ P = 6400 W ]
Hence, the power is 6400 W.
