Answer:
We will go in the same direction where the car was was moving before applying brakes
Our speed will be same as that of speed of the car before applying brakes i.e. 30 mph
This is due to law of inertia as we are initially moving with speed 30 mph so the due to inertia of motion of our body after applying brakes we move in the same direction.
Explanation:
As we know by Newton's first law that every object moves in its state of motion or state of rest until and unless some external force will act upon it.
Here we know that car is initially moving with speed 30 mph so our body has state of motion so it will have tendency to move in same direction.
Here when brakes are applied in the car then also our body will move with same speed in same direction due to inertia of motion.
So our body will strike with windshield with the speed of 30 mph.
The first two choices are both false, but the <em>second one</em> is the falser one.
All electricity sources do <em>not</em> have the same voltage. The outlet in your bedroom wall supplies 120 volts, but the USB port on your laptop only supplies 5 volts, and the battery in your cellphone only supplies 3.7 volts.
Answer:
B. 50/-8
Explanation:
The expression -50/8 is equivalent to;
-50/8 = -6.25
The expression; 50/-8 is also equal to -6.25
Therefore;
The expression; -50/8 is equal to 50/-8
Answer:
22.8077659955 m deep
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
g = Acceleration due to gravity = 9.81 m/s² = a
Time taken to fall through the foam
Distance is given by
The vat is 22.8077659955 m deep
