Answer:
6 seconds distance
Explanation:
When driving during inclement weather conditions such as heavy rainfall, snowfalls, etc.The minimum following distance must be increased to 6 sec distance. Moreover, during severe weather conditions the following distance must further be increased to a 10 seconds distance.
Answer:
Δv = 12 m/s, but we are not given the direction, so there are really an infinite number of potential solutions.
Maximum initial speed is 40.6 m/s
Minimum initial speed is 16.6 m/s
Explanation:
Assume this is a NET impulse so we can ignore friction.
An impulse results in a change of momentum
The impulse applied was
p = Ft = 1400(6.0) = 8400 N•s
p = mΔv
Δv = 8400 / 700 = 12 m/s
If the impulse was applied in the direction the car was already moving, the initial velocity was
vi = 28.6 - 12 = 16.6 m/s
if the impulse was applied in the direction opposite of the original velocity, the initial velocity was
vi = 28.6 + 12 = 40.6 m/s
Other angles of Net force would result in various initial velocities.
I think the correct answer from the choices listed above is the third option. The magnetic quantum number of an electron (m) designates the orientation in space of the orbital (electron cloud). <span>This number divides the subshell into individual orbitals which hold the electrons; there are 2l+1 orbitals in each subshell. </span>
Solid, liquid, gas and something else
Answer: find the answer in the explanation
Explanation:
It is true that the word “radiation" has a negative meaning for many people. Nevertheless there are many uses and significant benefits of radiation to humans. Below are some of the advantages
1.) Its application is useful in Agricultural and scientific research
2.) It is used to induce mutations in plants and animals
3.) It is used in treatment of cancer
4.) It is used to sterilize equipment in hospital and also food.
5.) It is used to study defect in metals and welded joint and to check metal fatigue
6.) It is used to trace underground pipe leakages.
