C because when the part gets out of the probe it would no longer stay contacted
Answer:
The mass of the block is 1250g.
Explanation:
Given that the formula for density is ρ = mass/volume. Then you have to substitute the values into the formula :

Let density = 250,
Let volume = 5,



A. There is less current flowing through the bulb.
Ohms law dictates that Electrical voltage = current x resistance. To understand current you would divide voltage by resistance. The less voltage the less current will run through the circuit.
Mark as brainliest if satisfied.
The answer would be c because a surface wave travels between two different materials, like air and water.
