Answer: 65mph, 75mph
Explanation:
Let us assume x to be the speed of the slower train, in mph (miles per hour).
Then the speed of the other train is (x+10) mph, according to the question.
We then would have an equation like this
1.6x + 1.6(x+10) = 224.
This is because, the first addend in the left side is the distance covered by the slower train.
The second addend in the left side is the distance covered by the faster train.
The sum is 224 miles, because they together covered all the distance to the moment when they meet each other.
1.6x + 1.6x + 16 = 224
3.2x + 16 = 224
3.2x = 224 - 16
3 2x = 208
x = 208/3.2
x = 65
Thus the speed of the slower train is 65mph, and that of the other train is 65 + 10 = 75mph
Possible terminal voltages are 6 - 1.5 =4.5 V or 6+1.5 = 7.5 V.
Voltage is the pressure from an electrical circuit's power supply that pushes charged electrons (present-day) thru an undertaking loop, enabling them to do work that includes illuminating a light. In quick, voltage = stress, and it's far measured in volts (V).
There are styles of voltage, DC voltage, and AC voltage. The DC voltage (direct modern-day voltage) usually has the same polarity (positive or poor), which includes a battery. The AC voltage (alternating current voltage) alternates between nice and bad.
Voltage, electric-powered capacity difference, electric-powered stress, or electric-powered anxiety is the difference in electric-powered capacity among points, which is defined as the work needed in step with a unit of charge to move a take a look at a rate between the two factors.

4hz is the answer i think atleast
8n downwards
since downwards force is greater than upwards just minus
Answer:
a) 12 N
b) 3 m/s²
Explanation:
m = Mass of the object
a = Acceleration of the object
Force
Now, F = 12 N
The resultant force acting on the object is 12 Newtons
The acceleration of the 4 kg object which is experiencing the same force is 3 m/s²
