Answer:
Phospholipids are able to form cell membranes because the phosphate group head is hydrophilic (water-loving) while the fatty acid tails are hydrophobic (water-hating)
Terminal speed is the maximum speed that a falling object can reach and is based on aerodynamic resistance. In a vacuum, an object falling toward a planet as a result of gravity will continue to accelerate until it hits the ground.
However, if the object is falling through an atmosphere, such as on earth, then it will accelerate up to the point that the aerodynamic resistance cancels the downward force due to gravity, and it travels at a constant maximum speed, called the terminal velocity. At this point, resistance is equal to acceleration due to gravity. At terminal velocity, the skydiver's acceleration is zero.
Answer:
im not 100% sure but i think d it makes the most sense to me
Explanation:
Answer: 42g
Mass will still stay the same because mass is a weight without pull of gravitational force. So whichever plant it is in, even in jupiter, the mass is going to be 42g.
Answer:
5600N
Explanation:
Given parameters:
Mass of car = 700kg
Initial velocity = 10m/s
Final velocity = 30m/s
Displacement = 50m
Unknown:
Net force acting on the car = ?
Solution:
To find the force acting on a body, it is pertinent we know the mass and acceleration.
Force = mass x acceleration
Now;
Let us find the acceleration from the kinematics equations:
v² = u² + 2aS
v is the final velocity
u is the initial velocity
a is the acceleration
S is the distance
30² = 10² + (2 x a x 50)
900 = 100 + 100a
100a = 800
a = 8m/s²
Therefore;
Force = 700 x 8 = 5600N
