Answer:
F=-50N
M=200kg
U=15m/s
F=Ma
a=F/M=-50/200=-0.25
V^2-U^2=2aS
0-(15)^2=2(-0.25)S
S=-225/-0.5=450m
V=U+at
0=15-0.25t
t=-15/-0.25=60s

Hope this helps, let me know if you have any questions!
Have a great day.
Answer:
the same type because they both formed from rock material.
Explanation:
The most precise method for determining the actual temperature of vaccines is to use a buffered temperature probe.
<h3>What is temperature?</h3>
Temperature directs to the hotness or coldness of a body. In clear terms, it is the method of finding the kinetic energy of particles within an entity.
Temperature is essential in all areas of Science right from Physics to Geology and also it is important in most parts of our everyday life.
The complete question is;
"What type of device should be used for measuring temperatures in a vaccine storage unit?"
A temperature monitoring system is required in every vaccine storage facility.
A buffered temperature probe offers the most precise storage unit temperature information, including a thorough history of how long a unit has been running beyond the advised temperature range.
Hence, the use of a buffered temperature probe is the most accurate way to measure actual vaccine temperatures.

Answer:
E. 0.25
Explanation:
Given that
Angular speed ω = 3.5 rad/s
Distance ,r= 0.2 m
Lets take mass of dust bunny = m
We know that
Radial force F = m ω² r
The friction force on the dust bunny Fr
Fr= μ m g
To getting slung off dust bunny from disk
m ω² r = μ m g
ω² r = μ g
3.5² x 0.2 = μ x 10 ( take g =10 m/s²)
μ = 0.245
μ = 0.25
Therefore answer is E
E. 0.25
Answer: A. It can only be motionless.
Explanation: When balanced forces act on an object, the object will not move. The only way that object can move is if the forces become unbalanced. Suppose there is a shoe on a table. You are pulling back on the shoe with a force of 3 newtons. But the friction from the shoe rubbing on the table is also 3 newtons of force. But the gravity pulling down on the shoe is also 3 newtons. Nothing will move. The only way the shoe can move is if you pulled with a little more force. The shoe would then move because the force you are pulling with is greater than the other forces acting on the shoe.
Ex 2: You are playing tug of war. Team a is pulling with 20 Newtons of force. Team b is also pulling with 20 newtons of force. The rope does not move. Team a starts to pull a little harder. Now they are pulling with 25 Newtons of force. Now the rope starts moving their way.
