Answer:
Explanation:
When the car is under an accelerating force and hits a tree, the instant force received by the tree is the same force that is accelerating the car.
The accelerating force can be calculated using Newton's second law:
Where m is the mass of the car and a is the acceleration.
A would be the answer
Suspension cables

Cardiogenic shock is a condition in which your heart suddenly can't pump enough blood to meet your body's needs. ... Cardiogenic shock is rare, but it's often fatal if not treated immediately.
Answer:
180 m
Explanation:
Given:
Uniform speed of the car, U = 30 m/s
Uniform acceleration of the motorcycle = 10 m/s²
For the motorcycle to catch up with the car, the distance traveled must be the same.
For the car;
Distance = Speed × Time
⇒ d = u × t
d = 30 × t
d = 30t ......(1)
For the motorcycle;
The stationary police motorcycle has initial speed, u = 0
From equation of motion;
but u = 0
.....(2)
Equating equation (1) and (2)
30t = 5t²
t = 6 seconds
Substituting t = 6 s into equation (2)
d = 5(6)²
d = 5 × 36
d = 180 m
The motorcycle must travel 180 m before it catches up to the car
Answer:
I take the thread and wrap it round the cylinder until it goes round the circumference of the cylinder.
Explanation:
I take the thread and wrap it round the cylinder until it goes round the circumference of the cylinder.
I then cut the thread at this length and extend it out on a table or floor.
I then place the length of the thread along the meter rule and mark of the position of its tip and bottom along the meter rule.
The difference between the bottom and top points is the circumference of the cylinder.
If the thread is longer than the meter rule, i mark off where the the length of the meter rule stops along the thread and then place the meter rule at that point and then mark off where the length of the thread stops.
The circumference of the cylinder is then 1 meter plus the extra measurement along the meter rule.
