Answer: 88 m/s
Explanation:
If we are talking about an acceleration at a uniform rate, we are dealing with constant acceleration, hence we can use the following equation:
(1)
Where:
Is the final velocity of the plane (we know it is zero because we are told the pilot stops the plane at a specific distance)
Is the initial velocity of the plane
is the constant acceleration of the plane
is the distance at which the plane stops
Isolating from (1):
(2)
(3)
Finally:
This is the veocity the plane had before braking began
Answer: I-131, P-32, Sr-90, Co-60 & Technetium.
Explanation: Isotopes like I-131 are used to diagnose goiter in thyroid gland and isotopes like P-32 Sr-90 are used for treatment of skin cancer and Co-60 for cancer and technetium is used to monitor bone growth.
1 is c
2 is false
3 false
4 i think is c ont 100% though
I believe the correct answer from the choices listed above is option C. X-rays have greater frequency than microwaves. In a electromagnetic spectrum, the order in increasing frequency is as follows:
radio waves,microwaves, terahertz radiation, infrared radiation, visible light, ultraviolet radiation,X-rays<span> and gamma </span>rays<span>.</span>
Answer:
i think its 1.5 m/s to the right?
