Answer:
Banking angle, 
Explanation:
It is given that,
Radius of the curve, r = 52 m
Speed of the car, v = 12 m/s
Acceleration due to gravity, 
Let the curved is banked at an angle of
with respect to the horizontal. It is given by :


So, the curve is banked at an angle of 15.77 degrees wrt the horizontal. Hence, this is the required solution.
Answer:
526.57 Pa
Explanation:
P ( pressure at the bottom of the container) = 1.049 × 10^5 pa
Using the formula of pressure in an open liquid
Pw ( pressure due to water) = ρhg where ρ is density of water in kg/m³, h is the height in meters, and g is acceleration due to gravity in m/s²
Pw = 1000 × 9.81 ×0.209 = 2050.29 Pa
P( atmospheric pressure) = 1.013 × 10^5 Pa
Pl ( pressure due to the liquid) = ρ(density of the liquid) × h (depth of the liquid) × g
Subtract each of the pressure from the absolute pressure at the bottom
P(bottom) - atmospheric pressure
(1.049 × 10^5) - (1.013 × 10^5) = 0.036 × 10^5 = 3600 Pa
subtract pressure due to water from the remainder
3600 - 2050.29 = 1549.71 Pa
1549.71 = ρ(density of the liquid) × h (depth of the liquid) × g
ρ (density of the liquid) = 1549.71 / (h × g) = 1549.71 / (0.3 × 9.81) =526.57 Pa
Sometimes, you can play sport for a longer time than you should. You should always stop and take a little break and always drink water. Also, if something starts to hurt, stop, let someone responsible know and take a break.
Answer:
b
Explanation:
they both have a neutral charge so they couldn't be positive or negative since that wouldn't come from anywhere
Answer:
Explanation:
Let's use the kinematic equation
s = ut + ½at²
Where
s = distance fallen
u = initial velocity
t = time taken
a = acceleration
Here the hammer is dropped so a = g = gravitational acceleration
u = 0 because the hammer is dropped.
So by substituting you get,
1000 = 0 + ½×10×t²
t² = 200
t = 14.14 s
