It would be c. As it can’t accelerate faster thus not having a faster velocity so it’s inertia
Answer:
Total energy = 1000J
KE = 500J
PE = 500J
Explanation:
As you may know, the equation for gravitational potential energy is mgh (weight x height)
If the skateboard is halfway down, that means it is at half the height. As the skateboard speeds up (as it goes downward), the potential energy becomes kinetic energy. Since it has 500J of kinetic energy at half way down, it means it had double that amount of Potential energy at the top (1000J). Since half of that became kinetic energy, there is only 500J of PE left.
Total energy = KE + PE = 1000J
KE = 500J
PE = 500J
Answer:
The cell membrane is capable of transforming oxygen and glucose into energy for the cell
Explanation:
The cell membrane encapsulates all the organelles of the cell. It provides protection for the organelles of the cell.
It transports nutrients into the cell and toxic materials out of the cell. It also prevents the entry of harmful materials into the cell.
The cell membrane does not perform the function of transforming oxygen and glucose into energy for the cell.
Answer:
Average speed of car will be 48 km/hr
Explanation:
Let the total distance is 2d
It is given that first half of the distance car travels with a speed of 40 km/hr
So time taken to cover half of the distance 
Second half of the distance is covered with a 60 km/hr
So time taken to cover second half of the distance 
So total time to cover 2d distance 
Average speed is the ratio of total distance to total time
So average speed 
So average speed of car will be 48 km/hr
Answer:8540 kg-g/s
Explanation:
Given
mass of blue car 
velocity of blue car 
mass of the truck 
speed of truck 
After collision they stick and lock together
Let v be the velocity of combined system at angle \theta from vertical
Conserving momentum in east direction
------1
Conserving Momentum in Y direction
-------2
squaring and then adding 1 & 2 we get
v=10.95 m/s
initial momentum of car
