Answer:
crust, and upper mantle
Explanation:
i had a question like this
earth's lithosphere includes these things
Answer:
This question is incomplete
Explanation:
This question is incomplete. However, the formula for velocity is;
Velocity (in m/s) = distance/time
The distance the car covered in the completed question is divided by the difference in the time interval
The difference in the time interval will be = 1.5s - 1.0s = 0.5s
NOTE: the distance must be in meters or be converted to meters
Answer:
The speed will be "1.06 m/s".
Explanation:
The given values are:
Momentum,
m1 = 244 g
m2 = 45.2 g
On applying momentum conservation
,
Let v2 become the final golf's speed.
From Momentum Conservation

Answer:
23.52 N
Explanation:
Using the Hydraulic Press formula
since the the liquid in an hydraulic press cannot be compressed
P₁ ( pressure at the piston 1) = P₂ ( pressure at piston 2)
P₁ = F₁ / A₁ where F₁ represent the weight of the car and F₂ represent the force applied at the 1 cm end and A₁ and A₂ are the area of the piston respectively
P₂ = F₂ / A₂
F₁ / A₁ = F₂ / A₂
(F₁/A₁) × A₂ = F₂
F₁ = 1500 kg × 9.8 m/s² = 14700 N
A₁ = πR² = π ( 0.25)² where R = 25 cm = 0.25 m for the larger piston
A₂ = πr² = π ( 0.01)² where r = 1 cm = 0.01 m
(F₁/A₁) × A₂ = F₂
F₂ = ( 14700 N / ( π 0.0625)) ×π (0.01)² = 23.52 N
