It’s because of refraction! the light bends at an angle and makes the straw look bent/broken. it’s just the way the light hits the glass that makes the straw look like that
Answer: Don't quote me I believe it's weight like mass and stuff
Explanation:
Answer:
Car collides.
Explanation:
The (negative) acceleration experimented by the car will be given by Newton's 2nd Law 
, where f is the friction force, which is the only force acting on the car on the horizontal direction. Its value is given by the formula 
since the normal force and the weight of the car are balanced on the vertical direction. All this gives us the equation 
To calculate the distance traveled by the car, we will use the equation for accelerated motion 
on the form (since it comes to a rest 
):
Which for our values is (taking the direction of movement as positive, which makes <em>a </em>negative, so we add a -1 to account for this):
Which means the car crashes against the tree.
Assuming g = 10, the weight of the sled is 720N.
If it takes 26.5N to just pull the sled, then the frictional force f is 26.5N in the opposite direction.
f = μ*720N
26.5N = μ*720N
μ = 26.5N/720N = 0.037 (2 s.f.)
First we should convert 14.4 km into meters using the conversion factor 1km = 1000m; thus, 14.4 km = 14,400 m. Next, we should convert all minutes into seconds <span>using the conversion factor 1 min = 60 seconds; thus, 40 mins = 2400 seconds while 20 minutes = 1200 seconds.
Speed = distance over time
Amy's speed = 14400 m / 2400 sec = 6m/s
Bill's time is 1200 sec + Amy's which is 2400 sec
Bill's speed = 14400m / 3600 sec = 4 m/s
Therefore, Amy is faster than Bill with 2 m/s difference.</span>
