Answer:
a. 10.2 N b. 1.73 c. 58.8 N d. 10.2 N
Explanation:
a. The force that will make the block slide down the plane
This is the component of the block's weight along the plane F = mgsinθ where m = mass of block = 1.2 kg, g = 9.8 m/s² and θ = angle of incline = 60°.
So, F = mgsinθ = 1.2 kg × 9.8 m/s² × sin60°.= 10.18 N ≅ 10.2 N
b. The coefficient of friction
The coefficient of friction, μ = tanθ = tan60° = 1.73
c. The normal reaction.
This is equal to the vertical component of the block's weight. So, F = mgcosθ. Substituting the values for the variables from above, we have
F = mgcosθ = 1.2 kg × 9.8 m/s² × cos60°.= 58.8 N
d. The frictional force
Since the block does not slide, there is no net force on it. If f is the frictional force, then
F - f = ma. Since a = acceleration = 0,
F - f = 0
f = F = mgsinθ = 1.2 kg × 9.8 m/s² × sin60°.= 10.18 N ≅ 10.2 N

Answer :
Average acceleration,
Average velocity, v = 13 km/h
Explanation:
It is given that,
Initial velocity of ship, v = 26 Km/h
Final velocity of ship, u = 0
Distance covered by ship, d = 5 km
Time taken, t = 22 min = 0.36 h
(a) Average acceleration,
So, the magnitude of ship's acceleration is .
(b) Average velocity,
So, ship's average velocity is 13 km/h.
Hence, this is the required solution.
Acceleration = (change in speed) / (time for the change)
Change in speed= (0 - 26 km/hr) = -26 km/hr
(-26 km/hr) x (1,000 m/km) x (1 hr / 3,600 sec) = -7.222 m/sec
Average acceleration = (-7.222 m/s) / (22 min x 60sec/min) = -0.00547 m/sec²
Average speed during the stopping maneuver =
(1/2) (start speed + end speed) = 13 km/hr = 3.6111 m/sec

Answers
Answer: 1.81 L
Explanation:
Let us assume that we are dealing with an ideal or perfect gas. Thus we can use the formula from Charles' law that relates the volume with respect to the temperature of a gas.
Given:
Initial volume (V1) = 2L
Initial temperature (T1) = 25°C = 273 + 25 = 298 K
Final temperature (T2) = -4°C = 273 - 4 = 269 K
Final Volume (V2) = ?
Using Charles' law like we stated above, we have
(V1) / (T1) = (V2) / (T2), making V2 the subject of formula, we have
V2 = (V1 × T2) / T1
V2 = (2L × 269 K) / (298 K)
V2 = 538 L.K / 298 K
V2 = 1.81 L

Answer:
The answer is C. Steer in a straight line while gently slowing down
Explanation:
The following are advised when your cars go off the pavement while driving;
firstly, Do not panic.
ensure you hold on to your steering wheel tightly.
keep Steering straight ahead.
ensure you Stay on the shoulder.
Ease up on the accelerator and brake gently.
When you know you can safely do so, turn back on the road at a much lower speed.
Final answer:
When the right wheels run off the pavement while driving, you should hold the steering wheel firmly, continue driving straight, and slowly reduce your speed. This avoids the dangers of immediately steering back onto the road or towards the shoulder.
Explanation:
While driving on a rural road, if your right wheels run off the pavement, the safe response would be to hold the steering wheel firmly and steer in a straight line while gently slowing down. Immediately steering back towards the paved surface (option A) can cause your vehicle to roll or veer into oncoming traffic. Steering towards the shoulder or ditch (option B) risks hitting obstacles or further losing control. By continuing straight at a controlled, reduced speed, you can safely return to the pavement when there's a break in the roadside or ample space to move back onto the road.

A substance that contains more hydroxide ions than hydronium ions in solution could have which pH value that would be greater than seven.
What is a Chemical compound?
The chemical compound is a combination of two or more either similar or dissimilar chemical elements
For example, H₂O is a chemical compound made up of two oxygen atoms and a single hydrogen atom.
A material with a pH greater than 7 could have a solution with more hydroxide ions than hydronium ions. As pH levels over 7 signify that a solution is no longer neutral, it has the same number of hydrogen ions as OH ions but more hydroxide ions than hydrogen ions. because it is simpler.
Thus, a substance that contains more hydroxide ions than hydronium ions in solution could have which pH value that would be greater than seven.
