Answer:
53 m/s
Explanation:
Since we take the positive x-direction to be toward the north, an SUV travelling to the south would have a negative velocity, -18m/s, relative to Earth. Velocity of Earth relative to the SUV would be 18m/s. And velocity of police car relative to Earth would be positive, 35 m/s.
Velocity of police relative to SUV would equal to velocity of police car relative to Earth plus velocity of Earth relative to SUV
= 35 + 18 = 53 m/s
C) During the radioactive decay, alpha particles are released. These positive particles are attracted to the negative plate in the electric field
Explanation:
In nuclear reactions, it should be known that the mass and atomic numbers are usually conserved.
²³⁸₉₂U → ²³⁴₉₀Th + ⁿₐX
This implies that:
238 = 234 + n
92 = 90 + a
When this is true, then the nuclear reaction is balanced. Both atomic and mass numbers can be said to be conserved.
Solving for n and a
n = 4
a = 2
Therefore
²³⁸₉₂U → ²³⁴₉₀Th + ⁴₂He
The particle resulting from the decay is an alpha particle. Alpha particles resembles a Helium atom.
Alpha particles are positively charged and they are attracted to the negative plate in the electric field.

The correct option is (b) 5n
A result, the object is being acted upon by a net downward force of 5N.
The force that is produced by summing the vector sums of all the forces acting on an object is known as the resultant force. The effect of the resulting force is the same as the sum of all the acting forces operating on the object. The direction of the forces must be considered when calculating the resulting force.
The northward force is Fn = 10N, given.
Fs=15N is the southern force.
The net force on the phone is Fnet =?N, which is necessary.
Downward pressure is applied by the object's weight, and upward pressure is applied by upward resistance. The vector sum of these two forces will represent the net force.
Fnet = Fs - Fn (Considering the direction downward as positive)
Fnet = 15N - 10N
Fnet = 5N
There is a net downward force of 5 N acting on the object as a result.

Qualitative data is easy to explain. You either agree or disagree in writing. Wrong. You agree, disagree, or qualify. Meaning agree to somewhat extend, but not entirely. So you can agree that people should walk instead of talk in the progressive manner, but not in the impulsive manner.
