Samburu's weight is (mass x gravity) = (1650kg x 9.8 m/s²) = 16,170 Newtons.
Samburu's contact area with the ground is (0.25 m²/hoof) x (4 hoofs) = 1 m² .
Pressure = (force) / (area) = (16,170 Newtons) / (1 m²) = 16,170 Pascal .
Answer:
A.) the photoelectric effect
Explanation:
Answer: t = 0.878s
Explanation: Dear big brain
since your temperature decreases linearly, you can assume that your velocity should behave linearly too. Here this isn't exactly the case (cfr. formula). But there's another way to prevent endlessly boring calculus. Use the principle of interpolation. (x/v_surface + x/v_top)/2 = t.
This answer won't be exactly the same, but it's a quite good approx. You can use this eqation, hence you don't use large distances.
Answer:
887.1Hz
Explanation:
Given parameters:
Speed of sound wave = 330m/s
Wavelength = 0.372m
Unknown:
Frequency = ?
Solution:
To solve this problem, we use the expression below:
Speed = Frequency x wavelength
330 = Frequency x 0.372
Frequency = 887.1Hz
Answer:
Explanation:
For answer this we will use the law of the conservation of the angular momentum.
so:
where 
is the moment of inertia of the merry-go-round, 
is the initial angular velocity of the merry-go-round, 
is the moment of inertia of the merry-go-round and the child together and 
is the final angular velocity.
First, we will find the moment of inertia of the merry-go-round using:
I = 
I = 
I = 359.375 kg*m^2
Where 
is the mass and R is the radio of the merry-go-round
Second, we will change the initial angular velocity to rad/s as:
W = 0.520*2
rad/s
W = 3.2672 rad/s
Third, we will find the moment of inertia of both after the collision:
Finally we replace all the data:
Solving for :
