Answer:
It is better to drive a large SUV in stead of a smaller car in icy conditions, because the large SUV contains enough friction of force to drive in the snow on the ground. The mass of the car also plays a huge effect on this because then it does not slide off the road. The large tires on the big SUV make you ride smoothly through the snow and ice. With driving a smaller car though, the old tires have already been through a lot of driving, so this makes driving the car rough on the road. This also makes it so there is not a normal force in the wheels, so this means the car does not go at its normal speed, and this could cause an accident, or the rough tires could cause a fire when driving.
Trust me on this. I am 17, and I drive a Nissan Armada as my first car. Life changing. Happy Holidays!

Answer:
Magnetic field, B = 1.9232 T
Explanation:
Given data:
Value of the charge, Q = 0.026 C
Speed, V = 443.592 m/s
Force experienced, F = 22.182
Now,
the Force (F) experienced by a charge in a magnetic field is given as:
F = QVBsinθ
where,
B is the magnetic field
Angle between the magnetic field and the velocity.
since, the velocity is in horizontal direction and the magnetic field is downwards. Therefore, the angle θ = 90°
thus, we have
22.182 = 0.026 × 443.592 × B × sin90°
or
B = 1.9232 T
Complete question:
(b) How much energy must be supplied to boil 2kg of water? providing that the specific latent heat of vaporization of water is 330 kJ/kg. The initial temperature of the water is 20 ⁰C
Answer:
The energy that must be supplied to boil the given mass of the water is 672,000 J
Explanation:
Given;
mass of water, m = 2 kg
heat of vaporization of water, L = 330 kJ/kg
initial temperature of water, t = 20 ⁰C
specific heat capacity of water, c = 4200 J/kg⁰C
Assuming no mass of the water is lost through vaporization, the energy needed to boil the given water is calculated as;
Q = mc(100 - 20)
Q = 2 x 4200 x (80)
Q = 672,000 J
Q = 672,000 J
Q = 672,000 J
Therefore, the energy that must be supplied to boil the given mass of the water is 672,000 J

Answer:
Straight Angle.
Explanation:
The two types of mirrors, i.e., concave mirror and convex mirror, acts in the same way when a ray is directed towards its pole, and the ray bounces back with the same intensity, and we get the exact same angle.
And, the initial angle and the reflected angle are exactly the same.
Hence, when the ray strikes the pole, in straight angle, then it forms a straight angle.
Hence, from the given option,
The correct answer is straight angle.
