Answer:
Heat radiates into walls and your belongings to get bed bugs in places that are hard to get to with insecticides Hope It Helps
Explanation:
Studies have shown that bed bugs can become resistant to chemicals and adapt to living in dangerous environments. This can make it a difficult job to treat for bed bugs with chemical products.
Since the velocity of the real plane is 0, p=mv=0. So the paper airplane actually has more momentum since it's value is not 0.
Answer: Choose the normal force acting between the object and the ground. Let's assume a normal force of 250 N.
Determine the friction coefficient.
Multiply these values by each other: 250 N * 0.13 = 32.5 N .
You just found the force of friction!
Explanation:
Answer:
The change in volume is 
Solution:
As per the question:
Coefficient of linear expansion of Copper, 
Initial Temperature, T = 
= 273 K
Final Temperature, T' = 
= 273 + 100 = 373 K
Now,
Initial Volume of the block, V = 
where
V' = Final volume
Answer:
wave length is 1.2m
Explanation:
since formula of wave length is v/f
v(speed of sound in air at stp is 300ms^-1)
f(frequency 250hertz)
then wave length is 300÷250 which give 1.2m
