Considering the forces acting on block \( M \) on the inclined plane:
\[ 10g \sin 53^\circ - \mu (10g) \cos 53^\circ - T = 10 \times 2 \]
Substituting values:
\[ T = 80 - 15 - 20 = 45 \, \text{N} \]
For block \( m \) on the other inclined plane:
\[ T - mg \sin 37^\circ - \mu mg \cos 37^\circ = m \times 2 \]
Substituting values:
\[ 45 = 10m \] \[ m = 4.5 \, \text{kg} \]
The driver sitting inside a parked car is watching vehicles approaching from behind with the help of his side view mirror, which is a convex mirror with radius of curvature \( R = 2 \, \text{m} \). Another car approaches him from behind with a uniform speed of 90 km/hr. When the car is at a distance of 24 m from him, the magnitude of the acceleration of the image of the side view mirror is \( a \). The value of \( 100a \) is _____________ m/s\(^2\).
A current-carrying rectangular loop PQRS is made of uniform wire. The length PR = QS = \( 5 \, \text{cm} \) and PQ = RS = \( 100 \, \text{cm} \). If the ammeter current reading changes from \( I \) to \( 2I \), the ratio of magnetic forces per unit length on the wire PQ due to wire RS in the two cases respectively \( F^{I}_{PQ} : F^{2I}_{PQ} \) is:
The logic performed by the circuit shown in the figure is equivalent to:
Let \( y = f(x) \) be the solution of the differential equation
\[ \frac{dy}{dx} + 3y \tan^2 x + 3y = \sec^2 x \]
such that \( f(0) = \frac{e^3}{3} + 1 \), then \( f\left( \frac{\pi}{4} \right) \) is equal to:
