moving with a velocity of 180km per
hour.
Calculate its kinetic energy.
The kinetic energy of the moving express train with the given value of mass and velocity is 7.5 × 10⁵Joules.
What is Kinetic Energy?Kinetic energy is simply a form of energy a particle or object possesses due to its motion.
It is expressed as;
K = (1/2)mv²
Where m is mass of the object and v is its velocity.
Given the data in the question;
Mass of the train m = 600kgVelocity of the train V = 180kmh = 50m/sKinetic energy of the train K = ?To determine the kinetic energy of the train, we substitute our given values into the above expression.
K = (1/2)mv²
K = (1/2) × 600kg × (50m/s)²
K = 0.5 × 600kg × 2500m²/s²
K = 750000kgm²/s²
K = 7.5 × 10⁵J
Therefore, the kinetic energy of the moving express train with the given value of mass and velocity is 7.5 × 10⁵Joules.

In a parallel circuit with three resistors connected to a power source, what would happen to the equivalent resistance and current if you removed any one of the resistors? the equivalent resistance would increase and the current would increase. the equivalent resistance would increase and the current would decrease. the equivalent resistance would decrease and the current would decrease. the equivalent resistance would decrease and the current would increase.
Since the equivalent resistance is decreased then current must be increased in the circuit.
What is resistance?Resistance is defined as the obstruction offered by the circuit in the flow of charge or current.
When three resistors are connected in series then the total equivalent of all three is given by
[tex]R_{eq}=R_1+R_2+R_3[/tex]

1. a weaker magnet will pick up more
paperclips than a stronger magnet
2. all magnets pick up paperclips, but the
number of paperclips depends on the
magnet
3. magnets will pick up metal objects but
not plastic objects
4. a stronger magnet will pick up more
paperclips than a weaker magnet
Answer: 2
Explanation:
The statement "All magnets pick up paperclips, but the number of paperclips depends on the magnet" is neither a hypothesis nor testable.
The hypothesis that is not testable based on the given data is magnets will pick up metal objects but not plastic objects. Option C is the correct answer.
The reason this hypothesis is not testable based on the given data is that the information provided only pertains to the number of paperclips picked up by different magnets. It does not provide any information or evidence regarding the ability of magnets to pick up metal objects versus plastic objects. Option C is the correct answer.
In order to test this hypothesis, we would need data or experiments specifically focusing on the interaction between magnets and metal objects as well as magnets and plastic objects. The given data only provides information about the number of paperclips picked up by different magnets, which does not support or refute the hypothesis about the ability of magnets to pick up different materials.

A motorist drives 5 km east then drives 5 km north. Calculate their distance travelled and their displacement.
Answer:
See
distance is 10 km
displacement is 5√2 km
Explanation:
DISTANCE:
Distance is scaler so, it doesn't depend on the direction
so distance is 5+5 which is 10
DISPLACEMENT:
Displacement is a vector, so, it depends on direction.
Now when we see north and east, they form a right angle, so we need to calculate the hypotenuse of the triangle for displacement as it is the shortest route between the two points.
Let hypotenuse be h
5² + 5² = h² Moved 5 km in east and north so values are 5h² = 25+25h² = 50h = √50h=5√2Hope it helps

Water is flowing through a pipe with a velocity of 5 m/s. The pipe has a diameter of 6 cm. The pipe then goes up 3 meters and narrows to a diameter of 4 cm. If the gauge pressure in the lower part of the pipe is 80 kPa, what is the gauge pressure in the higher and more narrow part of the pipe
The gauge pressure in the higher part will be 136 kph. The pressure is found with the help of the Bernoulli equation.
What is gauge pressure?The difference between absolute pressure and atmospheric pressure is known as gauge pressure. Relative pressure is another name for gauge pressure.
From the continuity equation;
[tex]\rm A_1v_1=A_2v_2 \\\\ \rm \frac{\pi}{4}(6)^2 \times 5 = \frac{\pi}{4}(3)^2 v_2 \\\\ v_1 = 20 \ m/sec[/tex]
The gauges pressure in the higher part is found as;
From the Bernoullis equation;
[tex]\rm \frac{P_1}{\rho g} + \frac{v_1^2}{2g} +Z_1 = \frac{P_2}{\rho g} + \frac{v_2^2}{2g} +Z_2 \\\\ \frac{80 \times 10^3 }{\rho g} + \frac{(5)^2}{2g} +0= \frac{p_2}{\rho g} + \frac{(20)^2}{2g} +3 \\\\ \frac{80 \times 10^3 - P_2 }{1000 \times 9.81 } = \frac{20^2-5^2}{2 \times 9.81 } +3 \\\\ P_2 = 136 \ kpa[/tex]
